CCleaner 2.13.720 Bug

I downloaded and install CCleaner 2.13.720 today. When I run a clean it comes up with this bug.

I've never had any problems with the last version. I ran it again and it shows the same problem. I did a restart and it doesn't show this time. I've never had to do a restart before, any thoughts? ;)
