[Bioangel]

I made a backup copy of my Diablo 2 because my kid destroyed my brothers play disc. It seemed to work fine until he downloaded the new v1.08 patch when it loads up it gives a page fault error (something to do with the FOG.DLL file ) so Ive tried to install dameon tools and the installer wont install it says i need to upgrade my installer this isnt true I have updated my WIN 98SE and also have installed microsoft office 2000 so I know i have it. Then tried clone cd database and Im not quite sure how to use that thing!? Well guys this is KICKING MY BUTT so I could use all the help u can provide!
