A couple of days ago, my Firefox browser started "acting up". Sites like this one here, that require you to login to be able to post, couldn't be accessed anymore. It gave somesort of error message about not being able to access the preference file or somesuch.
Now, I thought that perhaps there was something wrong with the folder, so I go, and find the folder protected (I don't have an english version of XP, so I don't know the exact name in english). I unchecked the box, but it reverted back the second I saved those settings.
So, now I re-installed Firefox. No luck. Only one thing was left. IE.

*Drama*
So, with IE I was able to login in sites like this. Hovewer, now I wasn't able to download anything. It only gives me that "not found"-error.
Now, the horrible thing is that I can't go back to check up on Firefox, to see if I can download with that, since I don't have the installation program, and obviously I can't download it anymore with the IE.

I think this might have something to do with the fact that I removed some obscure user profile that came with the computer (I bought it new, mind you). At least after that my browsers started acting up. I already tried the system restoration, but it only gave me an error about not being able to restore.
Now this wouldn't be a thing or two (for a while), but since I don't have any other P2P-programs other than BitTorrent installed, I can't even use them to download anything (attempt to download anything with the BT ends up in the same "not found"-error obviously).
Help?
