Tonight, I tried to buy a single track from the itunes store and I got this message: "You cannot buy because your account has been disabled. to continue using your account it must be enabled by the itunes store customer service. you can contact customer service at..." I don't understand what's going on? I bought music this morning using an itunes card from target and now all of a sudden my entire account is disabled??? I have like $800 bucks in music I've purchased from the itunes store and I don't want to lose it! I sent an email to Apple's customer service address and I've yet to receive a reply. Is this some sort of bug in the system??
