So I do have a really bad problem. All keys except moving and firing (and shield ) dont work. So redeploy, stats tab, instant action, chat, etc. The menu says they are set up correct. When I set them up again manually they work. But only once. Then they stop working again. . Next question: When I type an a (the letter "a") in chat my whole chat is deleted (the /yell part as well) and it only shows an a. Thanks in advance!
I assume this is a problem that is only occurring in ps2 so we can rule out that its not your keyboard thats the problem. If that's the case then try a fresh install. That will reset all your settings to default and should catch any missing assets that may be causing the problem as well at the same time.
