Do you have it in the fonts folder? (Control Panel\All Control Panel Items\Fonts)
I just opened up TD, clicked a cell, then next to the where it lists the font, I clicked the Red F. From there, I clicked 'show more fonts', where it brought me to Fonts folder, listed above. I would believe that if you put it there, you should be able to either see it from the drop down list, or select it from the fonts folder.
