Okay so maybe there is a bug here.

I have installed a full vanilla cart with zero addons, nor changes. The demo products are loaded.

I installed PP Express with PayFlow using the valid creds from the live site and the error persists on my fully Vanilla cart. In fact the only changes at all is to update the my store address etc on install and PP express, I didn't even update the currencies.

If the dev team could take a look, I would appreciate it.
