BeamNG Sandbox has stopped working...

I've already tried uninstalling.

Here's the log:

As you can see, the game is reporting a missing file.
"0.425692|Missing file: levels/main.cs!"

Also, I don't know if this is occasional, but it's also reporting this -
"BEAMNG| ERROR: unknown material: ICE
BEAMNG| ERROR: unknown material: SNOW"

Here's a screenshot.


Any solutions?

 

Try running the updater and if that doesn't work uninstall then install the game.

 

Unfortunately, I do not see an updater in the directory. Where do I locate it?

Here's a screenshot:

 

Oh. I dunno.

Just try reinstalling it then.

 

K, ​I will.

I re-installed it, but to my dismay, it isn't working. Thanks for the help, ​Cwazy!

 

Anti-virus off?
