you don't understand , i bought the original cd's , i have the original cdkeys , i just lost the cd's (only the d2 ones , i have the lod one ). I was asking if a cd-key is ment for only the game from the case you got the cdkey from or for any other pair of diablo cd's .
for instance : me and my friend both have d2 original , can i use my cd-keys with his cd's or do my cdkeys work for only my cd's .
for counter strike you buy the cd key from the shop and just download the game and use your legit cdkeys ? does this apply to d2 ?
