So I got the pre-order. I initially had problems playing online, ie. "code already in use". And the odd time the promotional code for the weapons would appear and disappear. Finally I got online to play and the weapons code didn't work, which wasn't a big deal. Played until level 6 and logged for the evening. Today I load it up, the weapons code works, and all the things I unlocked the evening before disappeared. Re-logged and I'm level 1 with nothing. What the hell is going on.

had this same issue, and it makes me not want to play mp if its going to reset everytime I log off, I wish they would adress this issue or acknowledge it

I totally agree... really frustrating to see no saved data for the MP. guess it's campaign until the issue is resolved... which is more trying to get my monies worth
