I flagged the admins to this they should be able to help you. Have you tried to email your support rep yet as you do get priority support from the developers with your pro.
Hi, thanks for reaching out. Our support team is busier than usual so it may take a while to get back to you. Please rest assured a team member will be in touch with you as soon as they can, and will make sure that the correct expiration date is in place for your license.
@Site_Mark: All of your licence keys, registration details, expiry dates and download links can be instantly checked here: https://www.ccleaner.com/support/license-lookup. Is there a key in there with an expiry date that looks right?
My Key has the correct expiration date when I check it on CCleaner's site. But my app did not show the proper date. Support just got back to me an manually corrected it and said one of their renewal servers was having issues. I am good to go now.
