The editor has a few bugs (it was only a development tool) so use the debug version
you could load the maps
room example.. build a bsp (press "p") then view the bsp light map (press "d")  Make sure you are in a room
   when you press d because if you are not in a bsp room you won't see anything.  You could always press d to toggle back
   It is possible to export the bsp to the simulator but only use the linefollowing one.

bestlinefollowing... you could take a look and edit it a bit if you want (linefollowedit) and export

To use the simulator all you have to do is import map (under file menu) and this picks up the BSPMap.bsp in the directory
and run the simulation on that file
