I had this problem very recently as well.
Nothing I found on here helped formy situation,
but I did do something randon that actually worked.

Install pro tools again on your computer...
After you install it, it will most likely say that it cant read the hardware.
So go to control pannel and click on uninstall programs

Right click pro tools and select "change" or "repair" something along those lines.

It will then re-install it WITHOUT having to un-install it first.

After everything was loaded and restarted......
It worked fine!

Give it a try and let me know if this works for you
