Are you trying to view the forums as a luker or under your own account? I don't recall the forums being locked to un-logged viewers but anything is possible.
Only other things I can think of that is causing you to get that warning/error is your IP address got put in with someone else ban. Or your account is messed up on its permissions.
Are you able to PM at farhad's? If not try here... maybe I can figure this all out.
