Fatal Lua Errors/Missing Game File

Hey guys, first post on the actual forum and I could use some help.
I've had consistent errors loading the dealership within career mode for some time, and get consistent Fatal Lua errors almost every time I load it. I ran the file integrity check and it shows missing 1 file. Is there a way to find/fix the missing file without fully uninstalling all files, and reinstalling them?

 

You can use Steam to verify the integrity of the game files

 

i also need help. I got a fatal lua error but no maps are showing up and when i try to go into garage or repository maps it just loads for ever. I have even verified if there was corrupted files and there were none . What do i do now?

 

Have you tried safe mode?
