Comodo System Utilities v4.0 Hangs On Loading

Noticed other people posted on this, but no satisfactory answer. Have CSU v4.0 and Windows 7. Worked fine for awhile. Now, out of nowhere, when I start the application - privacy, security and disk cleaner all just hand on “loading”. Doesn’t give me an option to do a scan. I tried uninstalling and reinstalling to no avail. Haven’t made any changes to my system of which I am aware that would cause any issues. Noticed a few people have had the same problem. Is why I hate these “cleaning” programs, no matter the manufacturer. Never found one that worked correctly. Any fixes out there? Thanks!
