Yes I can, but all your GUI triggers will be lost for example.
The thing is, WE work in that way, that everything created will be "translated" into script, so game engine can read it. "Map protectors" remove files that link script with WE interface so it can't be opened in WE but still readable by game engine.
I can deprotect your map, but all your code will be lost, if you don't know (v)jass you are doomed.
Sorry for bad news, but I hope you learned from this, all important data, should be stored on different folders (if possible hard drives so even format won't effect other files), cloud (hive pastebin, google drive etc) and on mobile phone and such, it won't consume much space (spare few MB for really important data).
