Damnit! For some reason my computer gotten all messed up. My guess is that when my anti-virus deleted a file, it must have been vital to my internet. In any case my browsers and msn won't work. I'll be able to make posts, but only when I am at school (like now). And summer vacation is next week, so I may be offline for a while. I have one hunch how to fix it, but if that does not work, then I may be offline for a while.
