I don't know if Shrapnel will replace the CD for free minus S&H if you send them the fragments, you could try. I would probably expect it, if say, my Diablo disk suddenly stopped working, and I know a guy who lost his, but had the CD Key handy. YMMV.

I suppose, if it happened to me, I wouldn't rush right out and buy another copy of SE4, even addicted as I am. I'd keep checking the Shrapnel web page, and see if the price was coming down, or just get SE5.

I'd save the fragments of the CD, maybe there's going to be some sort of rebate like there was for SE4 Gold.
