So I opened up radientand I thought I opened up my map but I actually overwrite an enpty map, i tried the app date mod folder and WaW root but when ever i open it up, blank map! 

Your map gets saved in map_source/mapname.map.
There is also a map_source/mapname.bak.
In the bin folder there is an autosave.map.
If they are 0kb or 1kb then you prob lost the map.
