How to edit the map in this situation?

[para0407]

Before I ask, I read this guide - http://forum.wc3edit.net/tutorials-chea ... 34777.html

I was going to add JJCP to the attached map

When I opened the map with the newest version of MPQeditor, it was shown "Read-Only". So, I could not change War3map.j file

And I tried to open the map with another MPQeditor which is in "usefool tools" in aforementioned guide, but it was not opened with the message that "the file or directory is corrupted and unreadable"

What I should do in this situation?

Should I unhex? or deprotect? this map?

Thank you

Try to rebuild the map by extracting files and remaking the MPQ.
