I can't log into bf2142

I just logged into Battlefield 2142 and joined a match, so there's nothing wrong with the servers.  Battlefield 2142 uses a different account name and password than Origin does, so make certain that you're using your Battlefield 2142 account name and password.  If you don't remember it, there are fields when you log in to Battlefield 2142 to send that information to your email account.
