Problems setting up PayPal as payment type

I've tried this twice now, each time, I get to the point where I set up a Billing Agreement with PayPal, but when I click on Return to Merchant I get an error. If I go back to the iTunes store, it askes me again to update my information. Its like it doesn't know I've set up the Billling Agreement with PayPay. Any ideas?

Thanks,
Alfredo
