So it said Unable to resolve server before, and now it says Unable to connect to server (Connection timed out). The SocksPort in your torrc is 9150. Are you sure it is 9150 in mIRC? I screwed up earlier when I said 9050 because I forgot it's different in TBB than in the standalone Tor client. Make sure it is set to 9150. Another question, do you get that error immediately or does it take 10-30 seconds to see it?
