help with decrypting , please

I want to decrypt lineage.dll's from ingame walker. Is it possible to decrypt and to edit?
Lowfyr provided with the link to some decryptor ([Only registered and activated users can see links. Click Here To Register...]), but the question is: is this the right tool for that and what about them decoding version (111, 121, 211, 212, 41xL, 41x)? Do I need to use some specific setting for specific walker version?
Thanks in advance.

why u want to decrypt the dll's, lol, there is nothin interested in it ;)

Just wanna try to figure out something. Please, any help whould be very appreceated.

i guess we cant decrypt it cuz we dont know which encryption is used ;)

btw for dll's u should try an hexeditor, cuz the problem is not the encryption, the problem is the hex code ^^
