Connection problems should be 1 or 5.
4 is firewall problems.
6 is either an error in the server code or maybe a proxy error (though thats only a theory).
TorJado please download
http://foxtrot7.com/updater/EIR_Launcher.exe and replace your current launcher.
This is a Debug version that will create a downloader.log file in the CoH directory. Post it here when you get that error again.
Thank you.
