Can't log in ETS 2 MP in Unsolved Topics Posted July 7, 2017 If your login isn't working even after you wrote it down on Notepad, copied and pasted, then you wrote it wrong. To make sure you are getting it right, logout of the site then try to log back in. If your credentials fail to login in there then you are indeed making a mistake somewhere. Double check everything is right. If it works there, then use the exact same information on the launcher's login screen. Write it down as @oolala11 instructed you, paste on the site to see if it works and if it does, use it on the launcher. As a last resort, uninstall the launcher, go to %programdata% and delete the folder "TruckersMP" then go to C:\Program files and delete "TruckersMP Launcher", download the launcher again, install it as administrator then run it as administrator and try to login again with the same credentials you use on the site.
