The bloody trainer won't worker on multiple games

I’ve been having this bullshit issue with the last few games I’ve tried wemod. I start the game through wemod and every time I hit a hot key to initiate a mod it just goes on then off and I am going to drop kick my bathroom door because of it.

Currently I am trying it on Medieval Dynasty

Can we have a list of games you’re having trouble with, as well as where you bought them from?
