Hi,  
thanks for your fast reply!   
I'm not using any antivirus.   
Today after several hours I was able to fix most of the issues.   
At first I ran into the wbemprox problem with the login,  
there after the problem with the webrtc_plugin.dll showed up. (VoiceChat) 
(big shout out to TheZog2 ! :thumbup:)   
Now everything is running fine in 2.5.6 exept the supercarrier.      
I uploaded 2 logs. 
The first without any carrier on the map (game is loading and running fine) 
and the second with the carrier (loading always canceled at 50%)
