Try this:

With XoloX closed to go Start > Run > Type in 'regedit' and press enter.

navigate to HKEY_CURRENT_USER > Software > XoloX.

Once at that the key , you will see many values inside the xolox folder. Click on the one labeled 'totd' and set the value to 0 ( Zero) .

Now start xolox up. Note that in the next build the startup hanging issue has been sorted.
