BF 2142 Registration with Origin

The BF 2142 login screen does not support any special characters, so if there's a ?!&£% etc. in your password, it won't match since these characters are stripped from the entered password in-game. I had that same problem a while ago, I went to pogo.com, logged in with my account, and then changed the password to something without special characters from the account management page.

Hope it helps.
