Tried to install a font from dafont.com, but as it was installing it said something along the lines of it having a serious error and cautious should be used if I want to install it. I cancelled it so it wasn't installed, and deleted the .ttf file. Just wondering what that means? Could it harm my system? I validated all my fonts, and some came back with errors, but it said that was just because there were duplicates and they should be okay.
