Ah, crap. Too bad I already un-installed L4D, and deleted it's directory folder. Would doing a system restore restore these things?
When I installed L4D, it wasn't the average installation progress. It extracted itself...
I deleted the whole directory after finding out after playing it, it was no good. Wasn't anything special. And prefered CoD4. So then, I checked the un-install wizard. Nothing, no L4D or anything. So I thought it would've been alright to delete the directory, and then it said it was being used by a person or program. I restarted my PC, then deleted the folder, and now, it is gone.
I tried Option 2 already. It didn't work. It is already set at 100% font size. Or even the Control + 0 .
I have a feeling, I may have deleted some fonts... Because I noticed that I don't have the Times New Roman font in my computer. After that, I started to wonder if it was either excluded from Windows 7 or if I deleted it somehow. I am thinking that I may have deleted it somehow since the Times New Roman font is very popular with not just students and people, even teachers prefer if you were to use that font.
Anyway, I know one thing, when it is a Steam Game, don't download it. If it is an average game that doesn't need to be installed in a special way to play it, then that's alright if you do. But now, I learned my lesson, never download Games that require special work for it to play on Multiplayer.
