How to import 3d Warehouse components into mySketchUp

How do you import components from the 3D Warehouse?
In the sidebar I see 3d Warehouse symbol greyed out as is “search 3D Warehouse”.

Did you try typing in the search line? The 3D Warehouse text is normally gray just as it is in regular SketchUp. Click in the window and type.

Dah!, thanks DaveR!
