Landscape paint not showing

I installed and ran the ark dev kit no problems, started to create a map all was working well have textures etc on and water but then when I tried smoothing a rock the launcher crashed, When I reopened the launcher and loaded my map all I get is the yellow outline no details nothing. I then restarted my computer loaded e[pic games launcher and it says install rather than launch. I tried to click install thinking it would figure out its already installed but it never it said file location must be empty. I then went into the file location and clicked on arkdevkit batch file and the editor loaded. Can someone please help as to why this has happened and how to fix it. I have tried loading new level and starting again and same problem :frowning:
