It's confusing because you mentioned the JAST version and the Steam trainer?
You do use our JAST trainer with the JAST version of the game? Please verify if the game was updated/patched. The trainer might be outdated.
There are no patches or updates that I know of for the JAST version of the game I'm running. No listing on jastusa.com
Is this because the Trainer and for the +12 version? That there are compatibility problems.
Please verify that our trainer matches your distribution platform as there is one trainer for the RETAIL and one for the STEAM version of the game.
