If map has read only tag it means its MPQ archive has been corrupted/optimized, so if Ladik's Editor doesn't work, try older version or try different editor.
I used MPQ Master to insert mapscript for this map, it can open most of maps that have weaker protection, some maps are protected against most known editors and the only way to insert files back is to rebuild MPQ which you can find tutorials for on Tutorials section.
Some also encrypt everything and crash editors upon opening so you need to unhex to remove these sort of protections but such maps are rare, mostly Korean/Russian/Vietnamese RPG's, good luck!
