I'm specifically working with the Doom 3: BFG Edition 184.108.40.20656 trainer but have had this issue with other trainers in this format as well. Do you just need to reset your binds each time you run the trainer or am I missing something obvious?
To clarify, the trainer is working great as they always do and regardless of the answer, I appreciate all the work over the years
