Yes, you do need to switch to advanced settings. I think it is under Tools>Configuration Wizard. Check advanced, and it will tell you whether you need to restart or not. Then go to Connection>Transport Encryption and select "Require encrypted transport" and set the level at "RC4." If you are doing this as an attempt to bypass Cumblast's blocking of bt traffic, it probably won't work. It seems like utorrent works a little better at this. Good luck.
