I tried to send the requisite files once before, but they don't seem to work. I have a strong feeling that Diablo II is copy-protected, so a legitimate CD is required for installation; not sure about online play.

I would've bought a fresh copy of both games over the weekend, but I had no money with which to do my purchase. If you happen to live near Philadelphia, and are familiar with Willow Grove or Montgomery Malls, the Gamestops there have a 50% off offer on both games, totalling a cost of twenty dollars.

Alternatively, you could find a way to illegally install DII, a CD-crack to play, and a CD-key-generator for both games. It might be easier just to buy the game. Less illegal and time-consuming, too.
