The editor won’t open the map.

Guys, help me out. I want to edit the map "Disputed Island" (A1M3). I accessed the data file, extracted it, but it won't open. I tried using extended mode, but it won't save. I've already downloaded a separate folder with maps, and it opens all of them except for "Disputed Island." What should I do?:smile45: :smile45: :smile45:
