Battlefield Bad Company Invalid beta code issues

Several Battlefield Bad Company multiplayer Beta testers for receiving ‘invalid beta key’ error messages when attempting to redeem their code on Xbox Live.

An EA forum moderator says:

"We understand that quite a few of you are getting an Invalid Code error when you try to enter your beta code on Marketplace. This is being investigated and I will update this post as soon as I have more information."

Lest hope its not Halo 3 beta all over again!!!
