Apple’s iTunes App Store is currently experiencing some problems if you have existing store credit and are attempting a purchase. I’ve been attempting to update some of my applications on my iPhone and I am currently unable to download my updates due to these problems.
The error reads:
Due to a problem with the iTunes Store, your store credit balance is temporarily unavailable for use in purchasig music; you may continue purchasing using a different method of payment.
Way to go Apple. And to think, I was finally starting to think things were coming together and then yet another infrastructure issue appears.

Yeah! I’m the exact problem, I wanted to get some new tracks and BAM. Some of the tracks were even FREE and I still had issues, I even had at least 14 dollars on my account. Dang iTunes I hope it gets resolved soon.>.>
P.S. I’m a lil’ mad lol. ’cause I rarely buy songs from iTunes and when I do this happeneds. Bleh.
The same thing just happened to me, I’m just trying to buy a music video and then that message popped up it’s christmas morning, and im steamed hopefully it will get resolved soon…
The same thing is happening to me now.
