Thanks for the reply Karthik! I have tried both approaches in Babu V's sugguestion and am still getting the "The file (file name) does not appear to be a valid font" error message. I am getting this for four of the seven font files I'm trying to install. All are purchased from the same site and are the same extension. I've contacted the company I downloaded them from and they were of little assistance. If you have any other suggestions, I'd appreciate it!
Many thanks!
