I do have been using the beta version and having Cleaner Validator problems.
On my 3rd reinstall of Vista and finally discovered that CSC is terminating my installation. I end up with a black screen with my cursor and thats it, every time I try to open an application. I know it is a Beta that I installed but the validator.exe is the problem. I did a scan on reboot with a new installed system and that’s where it all fell apart. Now on my 4th install and will give CSC a rest and see what happens.
It is a great program and am sure will be fine soon.
