Please Verify That Your Diablo Play Disc Is In Your CD-ROM Drive, Then Click On Retry Sigh... So I bought Diablo 2 & lod. Installed it on my laptop which has vista. After a few steps it worked perfectly. Then I get on my desktop computer which has xp. I install the game, try playing it, and it says that god awful error. After googling for an hour I see that other people have had the problem too, but I didn't find any solution. I installed the patch to lod and still says the same thing. I tried mounting a .iso file instead of putting my cd in, doesn't work. halp!
