Hello oCPR,
The first thing you will have to do is that you will have to edit some basic files so you can see the jobs,
Windows 7:
Step 1: Press the Windows key on your keyboard and type into "Search" Documents and press enter or click on the first option it will appear to you on your screen.
Step 2: After you have successfully navigated to Documents you will have to enter the game folder which is called Euro Truck Simulator 2, once you have entered the game folder navigate to Profiles and double click on your profile (it should have a weird number with capital letters etc...)
Step 3: Once you are in your profile you should find a text document called "config.cfg" or "config" after you find that file double click on it and it should open a notepad with a bunch of in-game settings.
Step 4: At this point press inside the notepad and press CTRL+F and a little menu should pop up and you will need to type this : uset g_force_economy_reset "0" after you have successfully found this line all you have to do is change the 0 inside the commas into a 1 and press CTRL+S to save the file or to be more safe in the notepad on the far left there is an option called "file" press on that and then press on Save.
Step 5: After you have saved the notepad you can close the folder/notepad and boot up into TruckersMP on your folder. When you log into your account and enter the profile it should say to you that some files got changed, press OK and then press on the Freight Market and all available jobs should pop up.
Windows 10:
Step 1: If you look closely on the far down left of your screen you should find a place saying " Type here to search " you click there and type Documents and press Enter or if that doesn't work click on the first thing that pops up. From here on go to the steps above starting from step 2 because it's the same procedure.
Hopefully I've helped you with your problem
