Error upon opening or using version 3.

After uninstalling version 2 from Win XPpro SP2, with VTP7, and Windowblinds, and after installation with version 3 of Comodo and following the fix for those with those programs on their systems, it still causes an error to pop up, everytime before I open or use it. The error says in the title bar of the error box: -x- cfpsbmit.exe-Entry Point Not Found-Then inside error box:The Procedure Entry Point is Thread Desktop Composited could not be located in the dynamic link library USER32.DLL. Any Idea what is wrong? Thankx. (B)
