PlayNC will be conducting maintenance Thursday morning. Players wishing to make changes to their Tabula Rasa and other NCsoft accounts will have to wait until the maintenance is over. You'll still be able to log in and shoot Bane, but won't be able to change your credit card. Here's the scoop from PlayNC.com.
On Thursday, February 7 at 9:30AM CDT (3:30PM GMT) we will be conducting maintenance on portions of the PlayNC website. Customers will not be able to access their PlayNC account during this period, and in-game purchases for City of HeroesÂ® and Guild WarsÂ® will not be possible. We anticipate this maintenance window to last about two hours. We apologize for the inconvenience.
