Sorry if this has been reported before (I couldn't find any posts about this).
There are certain songs/packs in the RB3 shop which gives an error when I try to purchase them. The songs have been released after RB3, so it looks like an unintentional error rather than license expiration. This is the error message I get (this is a translation, the actual error is in Norwegian):
"Sorry, this offer has changed. In order to purchase, you might need to clear the system buffer and restart. For more info, look up status code 80153016 on www.xbox.com/errorhelp"
I tried all steps at the xbox page (deleting marketplace file and clearing cache); I get the same error when I try to purchase the DLC again. Here follows a list of songs/packs which results in this error upon purchasing:
Cheap Trick - Surrender (live)
Dave Matthews Pack 01
James Brown - Super bad, pts 1 & 2
Phish - Stash
Queen - I'm in love with my car
Stevie Nicks - Stand back
Yellowcard - Only one
There might be more faulty songs, these are merely the ones I've unsuccessfully tried to purchase. One more observation is that the marketplace price is slightly lower for the faulty songs (in my currency they cost 11.80 NOK, while the correct price is 12.80 NOK for songs that cost 160 MSP).
