Problems With PayPal "My Cash" Card

I recently purchased a reusable paypal cash card from a CVS with a combination of cash and prepaid american express cards. Upon attempting to cash it in, I was taken to a screen that said only:

"NEED_MORE_DATA

Click here to return home"

Is there something that I'm neglecting to do? How can I fix this?

UPDATE: Called Customer Support, and was told by the automated receiver that the 10-digit PIN was invalid.
