I have download the map "X_Hero_Siege_3.11.w3x" from this site but i cant play it. When i try to open it (with winrar) the editor says: "impossible to load the program" and below "unit's dota not found or not able to be used" (in french: " impossible d'ouvrir le fichier" puis "donnees unites manquantes ou invalides").
Yes, it may be proteted, what you have to do is move the map into your wc3 maps file. Then you'll have to play it by getting on wc and playing it like any other game.
ok my problem was that i didnt know how to play a wc3 custom map.... To open the map i double clicked on the map file and the file was open with the editor...and it look like that its impossible to open with it because of a protection... So i did how "TheLastofMyKind" explained it and its ok now i can play !
