I had the same problem, but after looking at the name in the app I found out that there are 2 versions of D:OS 2. Classic and Definitive Edition. The trainer should say which one it is if you look and there are two versions, one for classic and one for DE. I found out that I was playing the DE version, but loaded up the Classic trainer. I know this sounds stupid but there it is if there are any problems I'll try to explain further.doesn't work? the app just says it cant find the game.
