Decrypt mpdata CoD4

[LoveMyslf]

I read the old topic on the old web site regarding this issue: http://old.zenhax.com/call-of-duty-mpda ... -t824.html
I lost my cd key, so I can't use the tool. Is there any way to retrieve my old cd key through mpdata? Or B: I bought a new copy of the game, can I in someway modify mpdata to become compatible with my new cd key?

Eh no, the cdkey is used to create the key necessary to decrypt the mpdata file.
So no cdkey, no decryption.

well all right, there's no way it can be hacked or recovered? thanks for answering

Hi Luigi

I try to use your cod4 decriptor downloaded from this link to edit my mpdata from Cod4 :
http://aluigi.altervista.org/papers.htm#codmpdatadec

all is ok and the program start and finish without error but the output file is this.
You know what is the problem?

Thanks so much

Decryption is correct but I didn't made any research on the format of the decrypted mpdata and the meaning of its fields.
