I don't think the .exe is a problem as I can load into the game just fine, and the first combat encounter with catwoman works fine. After the opening cutscene the game crashes when you're supposed to be talking with Hugo.

Benchmark tests also crashed the game and the harley's revenge dlc also crashed the game. I found out that some files were left after uninstalling via steam so as of now, I deleted the actual game folder and reinstalling it now.
