This is so pathetic, i got lot of chm files on my hard drive (useful stuff) but all these days, when i click them i used to get this 404 page, at that time i used to click other chm files and they worked fine.
Recently i felt like banging myself on the wall when i came to notice this in the properties.
When you download a chm from the web, XP automatically blocks it (isnt this ridiculous).
So you have to right click on the file and say unblock to show its contents.
This was frustrating, if i had known this earlier i wouldnt have missed many chm files.
