I had a 48 hour code for Xbox live (never used one before) but want to get the Fifa 10 demo. Anyway I put the card number in (25 digits) and it said it had gone through fine but would probably need to log out and back in to activate it. Anyway have logged out in every possible way (thought normal log out / through restarting the system) and it doesn't seem to have registered my 48 hours trial... What am I doing wrong? I have tried reimputting the code but it says it has been used. I can't find out where to check the code either as I don't think there is anywhere to do this...
