The ETS2 community (ProMods, TruckersMP, etc.) moves fast. Version 1.39 is now several years old; most modern mods require the latest version (1.49+) to function.
If you're interested in Euro Truck Simulator 2, I recommend checking out the game on Steam or the official website for more information on how to purchase and download it safely.

Unofficial installers are frequently bundled with malware, miners, or adware that can compromise your PC.
