I have the Slitherin purchased version and it's currently updated to 1.05. The trainer is not working. Has Slitherine done something to make this so? I should have known to buy from Steam but it was on sale
Have you tried registering your non-Steam game with Steam?
It's what I do when I buy a game elsewhere and want to have the auto-updating and such afforded by Steam.
Click on the "Add Game" in the lower left corner of the initial Steam screen and choose "add non Steam game".
