Quick update... I had to add in one line to cache the CC data stored by the core recurring fee handler. Now it seems to work fine on the Livetest.

I still need to tweak a couple other things on this module to make sure it's fully PCI compliant by default, but this should be a huge step for you in the right direction.

Grab it from Bazaar.

Summary: With the latest code, you should be able to operate as you were before. Look for a couple more changes to come to make it explicit what is and is not stored by the core recurring fee handler.
