when opening zero-k on the bottom it says:
disconnected due to network problem, autoconnecting..
this message would not dissappear.
i checked in the lobby log:
========================
1/23/2016 4:47:11 PM: ZkData.TcpTransport socket disconnected: The system detected an invalid pointer address in attempting to use a pointer argument in a call
1/23/2016 4:47:11 PM: Connection lost
1/23/2016 4:47:11 PM: Closing current battle
========================
i have posted this problem before, the only answer was an alternative lobby, where hosting battles was not possible.
