It seems from your post, that you have an issue with making paypal purchases on BlackBerry App World? Right? It has nothing to do with the PlayBooks and everything to do with App World. RIM has been aware of the error 11000 when trying to use Paypal on App World to make a purchase when your account is tied to a credit card.

Adding a financial institution as a secondary option has been successful for many users. Authenticating from a PC when trying to make a purchase in App World has also been successful for others.
