unpack client error

[minigutza 47]

When i try to unpack the archive "costum_pack" with eternexus i receive a common error in windows with "Send error report / Don't send".
When I used Easy File Extract0r by Eddy² 4 epvp the files are extracted without any error but are still incomplete (folders ymir work/pc2/warrior and sura are completly missing)
I think that the arhive is protected. May someone decript it for me pls ?

I don't know what "costum_pack" is, but you can't unpack the official type 4 protected files with the normal extractors. Take a look this topic for more informations.

Costum_pack arhive it's from my client but i think that somebody protected it.  Isn't from official client. Could someone extract it for me pls?

You can't extract your own client?
