how do you know what to fix im new to this and im not good with computer stuff and what do I look for in the v4 file because I cant find any trucks with gravedigger.material
alright so I downloaded the arm forces truck and it said missing grave digger band so I downloaded grave digger band and I copied and paste it into the armed forces document and it still wont work im using .39
when I download a single truck it pops up with missing pieces or crashes the game and brings me to the rigs of rods website and says error 5, im using an acer windows 8 computer can that be why
