Hi
This is taken from the solutions page - http://forum.ets2mp.com/index.php?/topic/15129-common-problemsquestions-please-read-before-posting/
If you do not have your own truck
Solution 1)
Go to My Documents > Euro Truck Simulator 2 and find config.cfg file and:
Change uset g_console to 1
Change uset g_developer to 1
Launch ETS2MP and select your MP profile and when you don't have any cargo/job, press the ` button which will open the console and type
g_force_economy_reset 1
and press ENTER. Then go back to profile screen and select the profile again and a message saying "Game Change detected" should appear which means it worked. Now once you're in, you want to open the console again and type in
g_force_economy_reset 0.
After that, just play and your jobs should be reset. If it occurs again, just complete the whole process again.
If you have your own truck
Solution 1)
Find a parking space and go to sleep (advances time by 8 hours in Singleplayer)
Solution 2)
Quick travel to one of your garages
Solution 3)
Go to sleep or call SOS
Solution 4)
Visit the individual companies and see if they have any jobs (drive over the green icon at the entrance of each company)
