MS has been sending out some nasty Updates of late.
Check and see if you have KB 3086255 loaded.
if so uninstall this.
And your CFS3 should run again.
I have a list of Updates for my Win 7 I was advised not to load, recently I had several issues with ALL my different CFS3 installs.
And after reloading the entire computer to factory spoecs, I discovered all the issues were from MS updates to Win 7.
