The free Yahoo API that our software has been using by default has now been disabled by its' developers. Likewise, we have disabled it for our users.
However, those of you who have been using their own API key need to turn it off in the
Preferences -> Search engines API keys menu section of our tools in order to be getting results again.

We are closely watching the developments and are going to make sure you keep getting relevant results no matter what data sources change in their operation.
Thanks!
