Wold Editor being unable to open

[Shadow_Heart]

Some maps I have (user made) will not open in my Editor, some will most won't. Now weither this is a problem or has something has prevented other people from editing. I am not trying to mess with or call my own on these, just that when i host these there is errors or things that make it too easy (ex: shop items cost too less, or items that need to go or something of that nature).
An example of what the editor shows:

Is there anyway to fix this?

should i just contact the remoder or what?

It is called map protection.

And we do not support unprotecting here.

If you want to open the map contact the maker of the map.
