i have to move your post because the problem you have is another problem , and we do like to keep the topic clean and clear with everyone his own problem 

 

that problem you have is probably the cause because your steam profile we cannot see if you do own ETS2 the main full game and not a demo

[Tommi1690]

So what can i do now that it works? I buyed it today...

[Tommi1690]

So i created now a Profil but I got the same Error.

 

And i bought it from mmoga and aktivated it on Steam. Its propertly the same thing.

[Tommi1690]

Can you look if your antivirus or firewall is blocking the API? api.ets2mp.com

I dont know how i can look for that.

 

Try to load http://api.ets2mp.com in your browser.

[Unkeyboardinated]

Go onto your firewall > Start button > Control panel > Firewall > check to see if its blocking the api.ets2mp.com

[Tommi1690]

Try to load http://api.ets2mp.com in your browser.

 

If i open the link it says: "{"error":true,"descriptor":"Invalid parameters"}"

 

 

Go onto your firewall > Start button > Control panel > Firewall > check to see if its blocking the api.ets2mp.com

 

I allready added at to them so the Firewall allowed it...

Wel i got same problem after installing the new upgrade 20200 it doesnt let me in annymore.

So the question is what did you do with te update?

 

My firewall opens the Euro Truck Sim.. 2 without problems i opend it so that he can do everything.. So the firewall isnt the problem.

And i played this morning on the normal beta version 20110 and this all happend after the new update its all gone.

 

Please let me know what other people did because i deleted steam and everything just to reinstall everything and still can't play!

[Tommi1690]

So with the new Update can i now play. Thank you for that. So i can easier wait for Fifa 16.

 

And a big Thanks to @TheFlyingDutchman who help me yesterday about 2 or 3 Hours with the problem.
