I've looked through the forums and I didn't see anything that seemed to cover this topic. Just to be clear, this is not a lifetime license. I renewed my licenses back in February for CCleaner Pro, Recuva, Defraggler, and Speccy. I received the email with my info and plugged it into the registration. Today I realized that my license lapsed. I tried to plug in the information again and it doesn't seem to be taking. I followed the steps for problem solving license issues and that still didn't work. I then tried reinstalling the applications and that still didn't work. Any advice?
Do also check https://www.ccleaner.com/support/license-lookup as I think you may have two currently CCleaner Professional Plus licences. If this was by accident then also ask support to merge those two licences for you.
