First of all the original CD of Diablo2 is protected by SecuRom new, so you should do the Image by using the SecuRom new-Option. I think you can choose this in the first screen of the Image-assistant in the last field on that page. You should also turn on the Emulation for Subchannel-Data under OPTIONS-EMULATION-EXTRA EMULATION befor you mount the Image of the Play-CD.
Hope this will help you.
PS: As you can see my English is even worser than yours, but just take it easy
