Yesterday I installed 2 vehicles mods, and worked perfectly and I could use the dlc cars. I was so happy about it. At night I shut my PC off. Today I turned it in and I installed 4 car. The game was crash. I deleted the last mod and the game is worked but there is no added cars moreover the official dlc cars are gone too. The trainerV says "invalid model" both of them. The added car spawner says there is no dlc because of the game version.
I don't know what to do.
