Well, he has the valley contents, but his game is still at the old version, when the current version is 18/01/02. He did uninstall spintires mod completely, cleared his cache, and verified the integrity of files. No luck what-so-ever. Any help from the focus + saber team is greatly appreciated.
Go into your game directory like this:
- Right click Spintires: MudRunner in Steam libary,
- go to properties > Local Files > Browse local files.
In your local files delete:
Right click Spintires MudRunner in Steam libary,
go to properties > Local Files > Check game file integrity / verify game files.
Let Steam finish the download and it should be good.
I did this for a friend who had the same problem.
