hi, sorry if this has been asked before -- tried the search function (and google!) but came up empty handed i've been using bits on wheels ever since i got a mac and it's worked for me without a hitch...until sometime last week, that is. it keeps telling me it can't connect to host. i tried downloading other clients as well: u torrent, vuze, transmission, tomato...all the same thing. the download refuses to start. what do i do?
