Looked for this crack everywhere.
Can't find it though... Does anybody have a clue?

Thanks!

I think it was nuked, which is probably why you cant find it.

Not nuked AFAIK. However all the crack does really is removing the keycheck and the call-home function. The protection itself was removed in 1.1 or whatever Doom 3 patch it was. Because the crack circumvents keychecks it is not available on Gamecopyworld since you need the original game anyway.
