I enter the 25 digit code, it says "This code entitles you to download Crysis 2 Limited Edition" providing some options and description, but after choosing the "Download Now" option, it reports status code: 8015400C.

Is there any known solution yet? Is it just me, because I haven't found references for XBOX version on this matter.

Cheers.

Yeah I'm experiencing the same problem and have not found a solution yet hopefuly they will provide one soon.
