Click START down in the bottom left (Assuming your running Windows), the control panel folder should be accessible from there.
If/When you find the fonts, I'd recommend moving them to your FONTS folder. If you don't know where that's at, click My Computer, select your Local Disk Drive, select the WINDOWS folder, then select the FONTS folder and move your downloaded fonts into that. This way you'll be able to access the fonts normally through programs like Paint and stuff....If you're still having problems, run the situation by in a bit more detailed fashion through PM.
