I am having the same or a similar problem.
I installed Bit Che, it said something about not detecting a torrent client, when actually I have uTorrent, didn't think that would matter, and I don't know if it's why I can't use it now?
When I try to search, the "search" button changes to "stop" for only a second, and the program does not seem to do anything at all? I can tell it doesn't even make a connection to the internet, as my firewall (comodo) does not report it attempting to connect.
So basically I cannot use this software.
BTW when I choose "show scripts F2", from the options menu, there are no scripts displayed in the side pane? Is this why it's not wokring for me? If so, how do I get some scripts in there?
