Worked for me!! Spent hours with everyone's attempts, looks like it is hit and miss: Mult. uninstalls, reinstall with anti virus off, use the TTclenaup Tool (did they misspell "cleanup" on purpose??), tried all this in/out of Windows Selective Startup Mode. I did not spend much time on the phone with TT support so I have no opinion. There's probably more solutions out there. Stick with it.
