Hello Geddam,
Can you give me some more information about your issue. When you say that Teststand "expires", what do you mean exactly? Are you ending the engine or closing TS, etc. If you can give me a more detailed description of what you have developed and when you are seeing a problem, I can better help you. Also, what version of TestStand are you using?
Thanks,
Caroline
