Fonts not showing up

Hello,

 

I'm working on coredraw x3 and when I try and use one of my installed fonts such as LHF Lincoln it's in the drop down menu but once I try and change text to the LHF lincoln font the sample text goes blank. When I find the LHF font in the drop down menu it doesnt show an example of the font style like the rest of the fonts I have installed. I tried to reinstall but no luck.  Any font I have installed that doesn't show a preview of the font, I can't use. Most of them are OTF fonts but I have other OTF fonts that work fine. Any ideas as to why a font in my font list shows up but goes blank when I try and apply the font style to some text?

 

Thank you for your help!!!
