well, i left this open for quite a while now. The gpu is already initialized, and now it says "connected to server using x.pushtrough xpt protocol". But it reports no activity, it's frozen there. Is this supposed to take that long too ? thanks and sorry for the insistance, i just want to know if i am doing sth wrong.

Now this happens when the server is unreachable (it says connected, but is actually connecting). Are you behind a firewall???
I have the default windows firewall, already created an exception for the miner, but nothing yet

Are you running with the default "example.bat"? If so, just remove the "-o localhost" option, since it is trying to connect to your own machine and not a pool. Sorry for that, I use an SSH tunnel to connect to the pool behind my firewalls and this config "leaked" into the example.bat.
