Today for some reason when I've tried to play iTMS files from both by iTMS accounts that my computer has been authorized to play for like the past year and a half it has said it is not authorized and i must authenticate! after doing this they play fine and the dialog which tells you how many computers are no authorized said only one was authorized, which is correct. iTunes even took files off my iPod from the other account before i realised that it had been de-authorised as well! what's going on?? the songs weren't even that old and i listen to/watch protected files regularly! anyone else experienced this?
