Many people have complained about problems accessing Adidas Live Season content(me being one of them).  I have been in contact with both EA and XBOX LIVE about the problem.  EA is aware of the problem, they told me to delete the file off my hard drive and re-download, which did not work.  XBOX Live told me to do the same, then perform maintence on my hard drive, which did not work either.  XBOX Live also told me to try using my hard drive and gamertag on another 360 and try and access the content, haven't tried it yet, if anybody has let me know.
