Hey, Azkarna. I’m currently running Infinity on Alien Isolation as well. The moment I launch the game with the program or if I even launch it after having started AI via steam it fails to load the mods into the game and crashes.
I dont think its an anti-virus or admin problem. I’ve tried those approaches.
Also. Considering the way the game crashes it reminds me a lot of what typically happens to CA games when you attempt to mod them. If anything is “keyword: out of date” the game will simply crash.
And this trainer hasn’t been updated since January. I think its possible some changes have been made to AI.
Again. Thats my theory.
If you guys at Wemod could update some of these trainers it would be awesome 
“Crossing fingers” I think that would fix it because the crash pattern resemble that of a mod not being able to register its intended game version.
