I bought the tomcat and after downloading it I went to fly it. As soon as i loaded up it said i had an impure client. Restarted and when i got in a server none of the key-binds respond. Trying to reassign them to the joystick they still wont respond. It works fine in instant action, can sweep the wings, turn on lights, etc, but multiplayer it just wont work for me. I hopped in the F-15 just to make sure and everything works as intended, system, lights, engine, etc. I verified the integrity of the files after a system restart. I don't know what happened, I'm stumped. Any help would be appreciated. Thank you.
