Screwed up with files

Recently i screwed up my BeamNG files. I overwrote the pickup file and some of the vanilla maps. Can someone tell me how to bring it back to delivery state. After reinstalling it just went back to how it was before reinstalling.

 

Steam or no steam ??

 

If through Steam:

OPTION 1 : Re-install by deleting the files via Steam ( Delete local game content ... )

OPTION 2 : Delete the files you modified by going into the game directory, then Verify integrity of Game Cache
