Black screen on 'Switch user' or 'Logoff' after installing TI 2015

Since I installed True Image 2015, I am no longer able to log off my current Windows session, or switch to another user. When I attempt this, the screen goes black, and the power save mode of my monitor kicks in. This goes on indefinitely, so I have to reboot my computer by pushing the start button for a few seconds, so my computer turns off, and then restart it.

When I remove TI 2015, the problem is gone.

Any help on this issue, would be very much appreciated.
