Bad Company 2 won't let me sign in no matter what

Im having this issue right now as well. it would be one thing to keep hitting retry, except every time i do, it forces me to input my DLC codes no matter what, so i have to keep inputting the code only to be told theres a network error, only to hit retry and have to log in and reinput my DLC code once again, infinitely. any fix for that??
