You might want to give this a try. It was a solution posted by Wizard1956 in January 2014. I had the same problem and this worked for me.
Uninstall CFX then copy the following into Windows Explorer and delete what ever is there. %USERPROFILE%\Local Settings\Stardock\CursorFX
Then try to reinstall CFX. It may be possible a corrupt cursor has wacked things.
