Missing the ME3 soundtrack from the collector's edition

Hey, 

I recently purchased the ME3 collector's edition, which I know comes with the soundtrack.  I followed all the instructions, and registered my game, but the soundtrack is not showing up under "your registered game content."  All of the in-game content works fine.  I should add that I initially bought the standard edition of Mass Effect 3, and I only just recently got the collector's edition.  I don't know if that might be why there is an issue.  Any input would be appreciated.

Thanks,

Rissa
