There seems to be a slight bug with the trainer, when I run the trainer and try to launch the game, before I even get to the main menu the trainer is crashing. It pops up a warning a couple of times, and then crashes and brings up the "Shut down" or "Wait" options that Windows displays for any program that crashes but doesnt completely shut down. I'm not sure what is causing this, but I have noticed that some trainers will actually crash if I close the folder that I keep my trainers in so it may be something similar to that.
Your framework could be the cause, to be safe, re-install all 3 of theses.
Have both latest .NET CORE Link (Both of the Net-Core MUST be installed x86 and x64) and FRAMEWORK Link from Microsoft.
