Your grammar is appauling, mate. Anyway, i think what youre trying to say is: "I cant open a map, its saying its protected. Is this because of my editor?"
If so, the answer is most likely not, as editors wouldnt differ when opening maps, the map-type they have to open is the same either way.
As for undoing it, there is a way, but I dont know how. I think its quite long winded too. Personally I wouldnt bother.
