Community Manager, Xbox EMEA Graeme Boyd hasthat the Midnight Club: LA DLC which slipped onto the Xbox Live Marketplace today was not meant to be available, and has since been removed.
"The Marketplace team has mentioned to me that a batch of Midnight Club: LA content went up accidentally on Xbox LIVE Marketplace this morning. It has since been removed, but you may have had the chance to download it while it was up there. If you did and if it's sitting on your hard drive you should delete it - reason being that it was being tested when it was mistakenly put live and therefore it may not work properly, the Achievements won't register and could cause you problems with your Midnight Club: LA game saves," said Boyd.
"Sorry for the mistake and sorry for the hassle, but if you did download the content best thing to do is delete it. I'll let you know when it's up for real!"
