Last week, I pushed the upgrade button for the Pro version. I paid the approximately $25. The charge went through to the credit card company. All that I got was a message that said my email was not valid. CCleaner got my money, while I got a silly message saying that my emails as not valid. I contacted support and complained. received a reply form my supposedly invalid email saying that they would get back to me. I am still waiting. No key. CCleaner has my money.
