Hi, there seems to be some sort of issue. I tried Google for this and found absolutely no solution. Basically, I cannot seem to install any new fonts at all. Any font I try to install or preview, I will get a message saying "Not a valid font". Now here's the strange part, if I click to view a font from the windows/fonts/ folder, it lets me view it of course but if I copy that font outside that location, like to my desktop, I will again get the same error, "Not a valid font". I tried logging on the built-in Administrator account as well to see if maybe I could do it from there, but no, same error. Anyone knows how to fix this?
