ALTERNATIVE SOLUTION
Waiting for a solution with these plugin stories.
Here is a temporary workaround so you can play on GPM.
Be careful, this solution will prevent you from using INEO and Conduent (ticket printer).
But the rest will be playable.
The solution is as follows:
Delete the files in the OMSI 2\plugins folder:
- GPM.dll
- GPM.opl
This will work much better.
Sorry again for this big inconvenience !!!
