Welcome to the community @mistermossa. 
WeMod automatically detects and applies which version of the trainer you need for the game.
Version 1.1.2618 is four versions out of date. Legitimately-purchased games from Steam will update automatically, so Iām assuming your copy of the game is cracked?
If so, this is the cause of your issue. Your copy of the game is not a Steam copy, for which this trainer is designed for. WeMod does not provide trainers for cracked games - nor does any professional trainer provider for that matter. See here for more information: No support for cracked games?.
