I recently (yesterday) tried re-downloading TDU2, because I f***ed it up by downloading the universal launcher for the unofficial patch (DO NOT DOWNLOAD IT!!!). So after I downloaded it yesterday, I tried to open the game but an error said that there was something wrong with logging into the servers BEFORE the game was entirely open (when it checks your network). Before you download the game, it says that to link your TDU2 account to the game, you need to login to the website. So I tried logging into the TDU2 website, but had to create another account with my other email. I am now downloading it again and crossing my fingers that it works.
P.S: I also deleted the game's folder in the location "C:\Program Files (x86)\Steam\SteamApps\common". PLEASE HELP!!
