Interesting. I read some of the posts here and what I find odd is that I just now got a pop up message that my license expired 1 hour ago after I updated (and I update whenever I get the chance). I checked my email and I purchased this on 9/29/2014. I also got another email that says, "Reminder: Your CCleaner Professional license expired on 29 September 2015." This email message was sent to me on 8/11/2016 5:35 PM. I however never noticed this message and it was marked as unread. However, I never got any pop up till today that it expired and I'm pretty sure I was using CcPro the whole time without any issues. Does this mean I won't get any more updates from today forth unless I purchase a new license? I checked my version number and its 5.56.7144. When I clicked on check for updates, it says I have the latest. However, I googled the latest version and its 5.56.7156. Whats the best course of action? Should I just keep this pro version as it is? Or is it more secure to just get the latest free version?
