1. Error opening archive! - MPQmaster
and thus I can't quite get the war3map.j out to insert the cheatpacks...

2. Reached the end of the file. - MPQeditor
another dead end it seems...

3. FATAL ERROR! - AutoCP3

4. Even if I manage to get the war3map.j out with MPQviewer, the question would be how to get it back in?
These are some of the problems I have in general with korean maps. Hopefully someone has an answer and thanks in advance!
