sorry dude .
hmm thought occurred .
and err this is prolly not the way things shouldbe ..
Blizzard does replace faulty/scratched/broken disks ..
what i dunno however is when you send them a scratched cd they send you a new one with a cd key ..
maybe some other regular knows this ..
i think they will only replace the disk and not send a new disk with a new cd key .
i am not too sure tho..
like i said maybe some other reg or moderator on this forum can shed some more light/in fon on this later on .
