Diablo 2 should remember the past! (Diablo 2)

Hello, tell me, is there where the people who still actively play Diablo 2 on off a server for example in Europe, which can help with pumping (the engine) , simply long-playing - all acts know even the account, but now can't remember neither the account neither the CD key...
But if you have one lying around off of a CD-Key I would be extremely grateful or could someone tell me who sells and helps to get it?
