If you're one of the people who popped open their brand new copy of Batman: Arkham City only to discover that the Catwoman DLC card was missing or the code didn't work, Warner Bros. wants you to give them a ring or drop them an email.

"All who are experiencing any issues with the game are requested to contact WB Games customer service Department by calling (410) 568 - 3680 , emailing support@wbgames.com or visiting community.batmanarkhamcity.com/support. All matters will be handled promptly," according to a "message from Warner Bros." posted on the game's official website.

The short missive also says that less than .5 percent of total games sold ran into the missing code problem.
