Troubleshooting Steps

If you receive the message about problems with internet connection and your company has the proxy, try to enable it in the registration form:

Also at the corporate firewall you need to enable the incoming and outgoing traffic over HTTP:80 and UDP:6001 ports to the machine where START-PROF is installed. To test the port 80 traffic please open the passuite.com web site on the machine.

Email with code was not received

If you didn’t receive the e-mail, please wait 10-15 minutes and check your spam folder. Some corporate email servers may block the emails from LMS@passuite.com due to it’s settings. Passuite.com email server should be added into the white list. In this case please try to use another e-mail, for example gmail.com or write to support@passuite.com or using the web form, we will help to resolve this.

In case of any problem you can ask developers directly using support@passuite.com, using web form or using social media Facebook, Linkedin.

Some of the typical problems with solution are described below.

Error message #60 “SERVER_PROBABLY_NOT_UP”

It means that PASS/START-PROF can’t reach the license management server (LMS) through UDP/6001.

Possible reasons and solutions of Error #60:

  • Windows Firewall or corporate firewall or internet provider firewall blocks incoming or outgoing traffic via UDP/6001. Change firewall settings to allow all incoming and outgoing traffic through UDP/6001
  • If failed, you may try to use mobile internet from your cell phone using the wi-fi hot spot to overcome the restrictions and firewall that block the UDP/6001 traffic on your laptop
  • If corporate firewall restrictions can’t be changed, then try to run PASS/START-PROF Trial from home

For any other problems that are not described above you may ask developers directly using support@passuite.com, using web form or using social media Facebook, Linkedin.

Error message “Internet access is absent”

It means that PASS/START-PROF can’t reach the license management server (LMS) through HTTP/80. To test the port 80 traffic please open the passuite.com web site on the machine.

  • Windows Firewall or corporate firewall or internet provider firewall blocks incoming or outgoing traffic via HTTP/80. Change firewall settings to allow all incoming and outgoing traffic through HTTP/80
    • Internet access is going through corporate proxy server. Need to specify the settings of the proxy server in registration form

  • If failed, you may try to use mobile internet from your cell phone using the wi-fi hot spot to overcome the restrictions and firewall that block the UDP/6001 traffic on your laptop
  • If corporate firewall restrictions can’t be changed, then try to run PASS/START-PROF Trial from home
  • What to do after installation?

    Once the installation is finished you can open the example models and review analysis results as shown below

    Also you can refer “How To” training video series for beginners by clicking here (20 videos):

    Or you can create your own simple model. It will not take more than 5-10 minutes from your busy schedule. Watch this tutorial video (from 02:45) for creating the simple U-shaped loop model and thereafter analyzing it.

    Also, you can create an underground or buried piping model (underground piping). It will take about 5-10 minutes. Please watch this tutorial video (from 07:25):

    Create an HDPE piping model (PE100). It will take about 5-10 minutes. Please refer to this tutorial video:

    Also, Create the FRP piping model (Wavistrong 55). It will take about 5-10 minutes. Please watch this tutorial video for help:

    If you already have CAESAR II or Autopipe model, you can open it with START-PROF. Autopipe mode should be exported into CII neutral format file. Also, you can open your Caesar II model. Please read this manual (opens in a new tab).

    1. Buenos días.
      Estoy haciendo un curso de estrés y flexibilidad con ARVENG. Esta empresa utiliza su software (un mes gratis) para realizar los ejercicios prácticos del curso.
      Actualmente voy por la mitad del curso, pero se me ha acabado el mes de cortesía que muy generosamente ofrecéis.
      Con el fin de poder acabar dicho curso, les ruego me faciliten otro mes de cortesía.
      Yo soy delineante proyectista y trabajo en CEPSA, concretamente en la refinería ubicada en San Roque (Cádiz).
      Cepsa, para realizar los cálculos (los cuales hasta la fecha se realizaban en Madrid, en el departamento de Piping ubicado en la torre Cepsa), utiliza CAESAR II,
      Con la división que está realizado internamente mi empresa, Cepsa está dividiendo la empresa en dos, por una parte Refino y por otra Cepsa química. Esta “separación de la empresa en dos” implica una duplicación y creación de nuevos puestos de trabajo, ya que antes, la oficina técnica de refinería, prestaba sus servicios para ambas partes y con la división de la empresa en dos, se ha tenido que crear una oficina técnica en Cepsa química, lugar donde trabajo desde el 1 de febrero (como trabajador de plantilla). En esta nueva oficina técnica (la de Cepsa Química), mi jefe (jefe del departamento de ingeniería de Cepsa Química) está apoyándose en mi para cubrir todas las necesidades de esta nueva oficina técnica, tanto en equipos necesarios (plotter, escáner formato A0,…), así como softwares necesarios, como S3D para modelar, SPPID para la delineación de los P&Id´s, Intools,…..
      Una de las necesidades que nos queda por definir, precisamente es el software que vamos a utilizar para resolver los cálculos de estrés y flexibilidad. Tal y como le he comentado anteriormente, me queda por realizar aproximadamente el 50% del curso, y ya que lo estoy haciendo con Arveng y estos utilizan su programa (Pass/Start-Prof), para mi lo mas cómodo una vez finalizado el curso, es contratar vuestro software en vez de tener que aprender a trabajar con Caesar II.
      Pero claro está, para yo poder pedirle a mi empresa la compra de vuestro software para trabajar con él en vez de utilizar Caesar II, lo primero que debo hacer es terminar ese 50% del curso que me aún me queda.
      Toda esta explicación que le estoy dando, es para que cedáis el programa un mes mas de cortesía (con el programa a full para mi PC).
      Yo no soy comercial (como le he comentado antes, pertenezco al departamento de Piping de Cepsa Química), pero creo que sería una buena inversión para vosotros (y por supuesto mas facilidad para mi también) cederme un mes mas la licencia de vuestro magnifico programa (muy intuitivo y de fácil manejo), a cambio de una posible compra por parte de mi empresa.
      Si queréis contactarme personalmente, podéis hacerlo en el siguiente correo:
      antono.fernandezm@cepsa.com.
      Esperando una pronta respuesta satisfactoria, les agradezco vuestra amabilidad por anticipado,
