I just fixed this problem:
3 important things:
log in Google Wallet
a) on the left side:
- "payment method"- there you have your adress with the creditcard
- open "more" than "address" - here put the same adress
b) on the top right side " settings" ( gear-ikon) here pout the same adress.
I had under settings another adress as the "creditkardadress". After changing it , my google music/movies works!!!!
