The above message and progress indicator go on as a never ending process. I can't upgrade the CCleaner. No issues with my PC or credit card. I can use them for all the other online payments.

Unfortunately, as this is a public user forum, questions about payments, billings, and so on cannot be answered here. Please contact our support team via the Contact Us form located here: https://support.piriform.com/hc/en-us/requests/new?ticket_form_id=86507 or by emailing support@ccleaner.com directly and we'll be happy to investigate this further.
