Why is the LEGO Rock Band disc required for export? I payed for the game (but traded it in) and have an export code. Plus, with all of the errors people are having through the LEGO Music Store, It doesn't make much sense. Nowhere on the box, the export slip, or the export site does it say "disc required for export download". You can't even tell if you need the disc through the Export Option in the Music Store. And it's not like you are coping files from the disc like RB1, it's just a download.
They should have made it so that you need the export file to access the option to purchase the export. They did that but they didn't do a very good job.
I also realize that we really don't know who is the cause for all of this (Either Microsoft or Harmonix).
Please let anyone who has the small export file access the actual export pack through Rock Band 1 or Rock Band 2. (e.g. You must have the small file in order for an option to come up in RB1/2 to download the export)
Please, somebody do something!
