mpq-editor help needet

I just downloadet "Ladik's MPQ Editor" then i loaded mpq's from the main wc3 directory and tryed to extract or open files.
Didnt work. It sais: Failed to extract ...blabla... (Error Code 5)
I'm new to mpq's in general so plz give me the hint i need or i will have to search forever to get it opened/extracted.

Hm, I don't know that error, you could e-mail the author of the program.
Or you could try PowerMPQ instead (see the thread somewhere above this one)
It's easy to use when you are new to this if you know WinZip or WinRAR.

I also tryed using the editor, It seems to be that it sucks.

Error Code 5 when ever I tryed to extract anything.

Use WinMPQ or another MPQ editor that has a working extraction method.
