I just updated to RC5 and updated webui also, but i got same problem with Webui just hangs and nothing else is happening. I have now tried to go back with Webui 0.361 and now i can load it. But i cant add torrents. I browse and find torrent file and press add. But the torrent never adds in utorrent. I have also tried with Utorrent 2.1 alpha, and same problem with adding torrents.
