@Richard Hatfield: It can be easy to lose track of things if you have licences attached to multiple email addresses - but you can always pull up your information (licence key, expiry date, etc) for a specific email address from https://www.ccleaner.com/support/license-lookup If you have accumulated multiple licence keys that still have time left on them then the good folks at support@ccleaner.com would be happy to merge and consolidate them for you - be sure to refer to "merge licence keys"
