Or you culd just edit an .ini file as I found out and posted here:

----------------------------------
You can get the game to work without having to disable your internet connection by modifying an .ini file where the game is installed.
eg.
C:\Program Files (x86)\1C Company\Off-Road Drive\PP3WorkGame\Config\
or
C:\Program Files (x86)\Steam\steamapps\common\off-road drive\PP3WorkGame\Config\
Open
DefaultGame.ini in notepad.
Towards the bottom find this line:
NatDetectionMode=
AUTO ;Supported modes: AUTO, FORCED, DISABLED
change it to:
NatDetectionMode=
DISABLED ;Supported modes: AUTO, FORCED, DISABLED
Save your changes.
Now the game will load without having to disable your internet connection.
