This messages just showed up when I tried to open the client. First the client appeared for 2 seconds, then shut down and opened the Updater_Downloader with the first message that says “couldn’ t establish a connection to the server”. Then open another window with the words above.
I just try to fix it with:
-Open as adm
-Checking the internet conection
-Checking the firewall
-The force update archive
-Even reinstalling the game
I think I’m the first to have this problem, cos I haven’t found the solution in the forums yet. If someone can help me I’ll be so grateful to you 
PD: as you can notice im spanish, so plz fogive me for my poor english, google translate is my bff
