Hey  

there is a new wine version out ( https://www.winehq.org/announce/1.7.52 ) and with that the connection to swc server
seems to work now, it says online 139 players now!
I have not tried playing or anything, and the interface is a bit buggy (active games list not working) but better than nothing.

Okay whatever that was it is not working anymore, has the same error like earlier now lol... wtf

I swear it was working few minutes ago, interesting
