I'm having a **** of a time with itunes and paypal. For some reason my payment method stopped working with iTunes, that is paypal. So i have an outstanding balance of .99 from my last download.

I set up paypal as my payment method in iTunes, and i'm pretty sure my Paypal is fine... it's based on my checking account which has plenty of money... but i create a new profile each time iTunes prompts me, which just leaves me with a bunch of new merchant profiles for iTunes in Paypal>Profile>pay list... each of them say balance as primary source... my balance is zero. But it always was; don't see why that should hold me up. I set the backup source as a current credit card. Still no dice.
Have you encountered this? Can you tell me how to resolve? Thanks so much for any help.
