Cannot load VI in teststand.

This is part of a big project that was created before me, i just joined the company and has to work on this and i cant make such big changes. But for future when I am working on my own projects I will use .lvlibp.
I use LV2017 with teststand 2016.
The config VI is runnable, as I said, I run it one time, it works and then the error appears which is what i dont understand. Then I have to close teststand and run again.
