I'm still unable to pay with PayPal. Sam has not responded to my emails. Seems like some of their payment scheduling plans backfired a tad. Hope it gets resolved.
Good luck Sam!
After a few calls with Mastercard and Paypal I was able to send the payment directly to KnC's Paypal email address. I was unable to use the 'Pay' button (from the order detail page) on the KnC site. Sent directly from within Paypal.
