WindowBlinds changed my font faces?

Okay so, on a whim last night, I decided to clear up all of the un-used programs on my computer, which included the trial version of WindowBlinds I had installed a week or two ago. I wasn't ever really big on it, seeing as how I didn't have the money for it, and after I deleted it I turned off my computer. However, when I turned it back on this morning, I came to discover that the font for my programs, Firefox, and my computer had been converted to either boldface or italics. When I went in to see if there were any changes to the appearance settings, it showed nothing at all. I went as far as to do a system restore to see if it would help, but there was no restore point for when I had deleted it.

Has anyone ever heard of this happening? I've tried searching Google for some help with the problem, and come to no solution whatsoever. I'm baffled as to why it happened, and I assume that WB is the culprit, due to the fact that the only other things I deleted were Spore and a trial of WinZip. Can someone, perchance, help me out here?

With all due respect,

Holly D.
