It connects, I get the "pay now" screen.

I log in.

I get the pay screen with the payment method choices at Paypal

I choose my Paypal credit card

I get the "Pay with Paybal master card screen with the invoice total, I click "Pay Now"

I get the processing circle, then get sent back to the payment methods screen.

The payment never gets made.

I eventually cancel and return to Renderocity after hours of amusement cycling between the two screens.

It looks like the problem was at Paypal's end.  When I chose a different credit card the payment went through.  I'll contact them about the problem.

it's not working for me either. I refuse to use my bank card at rendo due to prior security problems with them.

I was able to process through Paypal, just not with their credit card.  I could use a different credit card I had attached.  I think the problem may be communication between the paypal site and Synchronicity bank who does their credit card.  There may also be a glitch in the routine that works with a paypal credit balance in conjunction with their card.   In any case, I don't think communication between Rendo and Paypal is the problem.
