Except that it's impossible to enter a player name or email address/pass (for Multiplayer registration). I'm experiencing a strange issue where trying to enter a player name for the campaign does not work: even with the name box selected (the cursor displays there), it does not register any keys entered. Same goes for Massgate multiplayer registration.
However, going into the option menu and remapping keys works just fine--it registers key presses and changes the keymap appropriately. So it's not as if the game lacks focus, or can't recognize the keyboard. What else might cause this issue?
