When I try to export the songs, I get an error saying that there is a problem with Xbox LIVE. The message is as following:
(X) Xbox LIVE Marketplace
There's a problem with Xbox LIVE
Marketplace, Please try again later.

Status code: 800700E8

OK
Is it just me getting this error or is there a problem that Microsoft or Harmonix has? The Xbox LIVE Marketplace was down 2 days ago, I think, but works now. I have successfully exported the songs from Rock Band (original) and shows up in LEGO: Rock Band in the Free Play and Story.
Are there other here who are experienced with this kind of error and knows a workaround?
