Alien Isolation Trainer says 1.0.0. Yet the updated one is 1.9. Failed to update?

The v1.0 is the version of the trainer itself which is the latest, v1.9 is the game version.

I trained the game on latest steam version at time, i don’t think the game had any updates since that time.

Can you post the exact error you get ? Also please give the best practices a read and follow them, this trainer shouldn’t have any issues but i’ll check it out again
