It was not a spaces problem, but by the way I solved it and now I would like to share the solutions if anybody has got the same problem as I did.
The problem is that when extract the two archivies (base and extra) you have two directories:
World of Metin2 Client for metin2dev.org - Base
World of Metin2 Client for metin2dev.org - Extra
Now inside the base one you have three other directories:
Client
Server
Tools
And inside Client once again three directories:
bin
data
launcher
Now, when you compile the FileArchivier tries to go inside "../bin/pack/" but if you are trying to compile from the "Extra" folder you can not find it because that directory does not exist, and there you get the problem.
The solution is very simple, and you can do two things according to what you prefer:
Create a "bin/pack" folder inside the "Extra" folder and then move the pack files manually
Simply compile all inside the "Base" folder
I know it is a stupid error, but I wanted to share anyways
