D3DERR_DEVICELOST (map creation)

The game gives me a D3DERR_DEVICELOST error, seen in the second image.

It's the second time this problem occurs. I checked the error page at http://wiki.beamng.com/Errors/-2005530520#D3DERR_DEVICELOST but without any particular luck in understanding what was going on. Also the page says that the device attempts to recover. Buuut the game instead crashed and made me lose all my progress.

I tried to use the editor to make a "decorated" version of the default track in the Demo (since I can't buy the full game due to the payment options... and money), so I figured there shouldn't be any problems. But upon moving closer to the map to take a second screenshot, I stumbled over the error again. The first time it also happened when I closed-up on the map, so I suppose they are related. But I'd like to know what caused the problem because as far as I know Beam.NG Drive has a clearly huger map with more detail put on close-ups.

I'd also like to know how could I prevent this error. The page above has close to no understandable explanation and methods of preventing the error. Not to mention false information regarding the device recovery, the game just crashed to desktop.

Much appreciated, this game is fantastic and I love the Torque3D editor.
