Kimberly,
If Ulead is anything like PSP it uses your system fonts.
Ok, so the big question is how do you make the TTKlingon fonts become part of the system fonts? Simply copy your fonts files then follow this directory C:\WINDOWS\FONTS and paste (this is with XP--if you're using 98 or ME I believe you'll find the Font folder in your control panel).
Fire up Ulead and viola, you should see your new fonts offered in the font selection screen/panel/dialog box.
HTH.
Best,
Jerry
