Well, that was weird…
No problem downloading, installing and registering the program, but…
It chugged away for about 30 minutes scanning my C drive with about 1 TB of data, but then just shut down. When I tried to open the program again, no dice. I cannot get it to start up again. I tried to Run as Administrator too. Nothing worked.
Sadly, another UNINSTALL candidate for me.
Thanks for the chance to try it though.
