Unable to install fonts using Corel Font Manager on my new Dell XPS Windows 10 computer

Hello to whomever,
I recently upgraded to CorelDraw Graphics Suite x8 from the x6 version.  Since doing so I have been unable to install additional fonts on my new Dell XPS i7 computer running Windows 10. When trying to do so through the Corel Font manager program, my computer crashes and reboots every time. I tried to use the x5 bitstream font manager program with no success. Crash and reboot occurs.  Please help. I hope I have supplied enough info to get an answer. Thanks.
