Problem with new install of pro

I recieced a notice to renew my License for Pro CCleaner, but when I went to renew the offer was for 3 computers at a special price. I only have one computer so I bought a new download for Pro. When I went to register, my old one came up with my old registration! I cannot find a "Contact" link for help! HELP!!!!!!!
