We are planning on performing maintenance on our billing servers on Monday 11 Feb 2013, from 6:30PST to 12:30 PST.
During that time you may experience any/all of the following:
AP showing as ERROR/-1/0 (Depending on location)
Unable to purchase any AP (from billing page, or offers)
Unable to spend any AP (either in game or via webmalls)
Unable to redeem any items from webmall related functions (Free Loot Box, Tiered Spender, Loot Wheel, Loot Forge, Bonus Ladder, etc)
Other Misc errors related to billing
In addition to these issues, some games may require a restart after the maintenance is complete to clear any errors. Do not be alarmed by any of these issues, as they are purely temporary, and will be resolved when maintenance is complete.
