2142 Battlefield

Ok first off, why in the WORLD would you not support 2142 Battlefield but still support 1942 and release it for free? You can take that up with the higher ups by the way cause I'm sure you have NO clue on why that is LOL. 

Anyway, I just bought 2142BF from Origin, and tried setting up a user name/password and all that but it wont let me, it keeps giving me "That user name is already taken" and I've tried random lettering, real words and so on. Can you please assist me, as my clan and I are getting back into the game, and I'm betting your going to see a mass wave of people trying to get back into 2142BF. 

Second, where do I got to change my email address in Origin? I've since cancelled my old email service and wish to update to a new one where I can get my notices and everything else if I need.

Thanks
