I, too, just updated RootSearch to the latest version from MathSource, 
and none of the examples in RootSearchExamples.nb gives an empty list.

Note that the new version is installed as

   ExtraPackages`Ersek`RootSearch

whereas the previous version was set up as 
ExtraPackages`Enhancements`RootSearch`.

Do you by any chance still have the older version in that latter location?
