ok I've about had it!!

I've been trying to download and install a font for the last hour and it's not working. I've downloaded/installed many fonts when I had XP before so I do know what I'm doing.

Now I download the font in a zip file, extract it to the Font folder, and nothing happens. I've tried extracting it within my Downloads folder and moving it manually to the Font folder, and I've tried downloading it directly to the Font folder, and nothing is working!!

Does anyone know if their is a compatibility issue with downloading and installing fonts with Windows Vista?
