ok first, you 2x legit *bought from store* cd-keys
download the onlyer-s cdkey changer from d2sector.net underdownloads.... instructions are inside.
what i did, was download it. *if u f***ed up re-download it again b/c the special MPQ file may be messed...* then input 1 only new set of cd-keys *yur main is already used to play* change the owner name. save it. register it. copy the MPQ file to d2 directory then use the application to "refresh both cd-keys" or w/e it says. *(should flash. if it doenst u did it wrong.)* then THEN
u need d2 lloader
make 2x shortcuts
*follow instructions from onlyer's read-me inside* it says to make 2x shortcuts which one of them has a different TARGET setting. adding at the end of the, which right after it says Diablo.exe YOU add -cdkey.mpq
"C:\D FOLDER\Diablo 2 new lod\Diablo II\Diablo II.exe" -w -mpq cdkey.mpq ***this is my location to where i load the game. and it loads the cdkey..***
the second shortcut should be same but named differently and doesnt need -mpq cdkey.mpq

ONT ADD IT:
so now u should be able to do it. run 2x windows. 2x more fun

hoped this helped.
