Hi,
Thank you for the quick response.
From within CCleaner, I followed the path described in this link. https://support.piriform.com/hc/en-us/articles/360020674812-How-do-I-manage-my-CCleaner-subscription-#how-do-i-manage-my-ccleaner-subscription--0-0
As follows:
Options > License Key > Manage Subscription > Auto Extension. I clicked on Cancel next to the Auto Extension field and was taken to a verification page where letters are required to be typed in. I did that and clicked on the Send New Link Via Email.
I got the email but when I tried to use it, it took me to an error page. Suggested errors from the error page were page no longer found in the server, link invalid or wrong, link entered incorrectly or page doesn't exist anymore. It said to inform the site owner that there's a problem.
Note that I tried this twice from two different computers, four times total. Same result each time. In both cases, I used Firefox with the same security settings and same extensions.
Thank you.
