When I start the game in sngolplayer or multiplayer the rf2 logo appears and then closes. It always worked well and I did not do any updates or installed new programs. Do you have any solutions? Thank you very much
Try moving the entire contents of your userdata folder somewhere else, verify rf2 files through steam, and try again. If that works you can later move some of those files back in to restore your history and settings, keeping in mind the .JSON files especially might be broken.
