I'm trying to play the original C&C3 Tiberium Wars. It's been a favourite game for many years. But just today when I try to play I get a message "Sign in to your EA account to activate your game on this computer". I put in my credentials, then I get an error message, "The game cannot start. In order to launch this game, please login to the EA Link to verify your ownership, then try again." The details I enter are correct - I can sign in to EA with them. They've not changed since the weekend.
I appreciate that this is an older game, but if you've deprecated it - I notice the link to the C&C forums now does not work - can you please supply a patch so it doesn't ask for credentials and can be played offline?
