Map editor trouble

[Shock]

I've been making map for a hour already, sadly that i didn't save it... What happened?
-Map editor just crashed without any message and game was closed automatically.

I have tried to remove list images, still doesn't work.
Now i'm trying to open map editor and game crashes every time when i open it.

Try to restart your computer first if the map editor won't start again and it just randomly crashed.

I fixed this trouble by changing the resolution in SFD, i use windowed mode always.
