Have had this problem for a while now. When I join any coop server, i would be able to type for a few second(5-10s depends on the ping) then I won't be able to type anymore. I can still open chat, but when I send the word it just doesn't show up in the server. I cannot use any command( !cp !buy etc.). However, I am able to chat like normal in Versus and Scenario server. Not sure what is causing this server side, my side, or am I banned from chat(lol?). Things I have tried: 1. Unbind key/set default key 2. Verifying Integrity of Game Files 3. Deleting config.cfg 4. Reinstalling the game All of these didn't helped me fix the problem. If anyone have any ideas on how to fix this problem please tell, I would like to become active again.
