I had to Restore my PC to before I bought CCleaner Pro. So I need to reload CC Pro. I have found both sites about how to reload License Key and but I can't find the actual form where I need to enter that info, please send me that web address.
If your licence is still valid then the 'form' where you enter it is in CCleaner itself, Options>About>Upgrade to Pro.
See this article for how to register CCleaner:
If you mean that you can't remember what your registered name and/or licence key is then you need this page (and yes it could be easier to find):
https://www.ccleaner.com/support/license-lookup
To use the licence lookup you do need to use the email address that you used when you bought the licence, and the licence will be reconfirmed to that email address.
If you cannot access that email address anymore then you will need to contact support from your new email address and tell them what that old email was.
