hello Mark,
I had the same problem with the first Beta.
please verify that you have the fonts in Fonts:_ttf , if you don't, the problem is here, create the folder and place your ttf fonts there. If you have the folder and fonts in there and still don't work, fonts are corrupted, replace them with good ones.
PM me if u want me to send you the fonts.
