.... you might want to consider upgrading. SketchUp is changing the way older software versions access outside applications, namely Google Earth and the 3D Warehouse.
You can read details here.
If you use SketchUp 2014 or 2015, there are no changes.
If you use SketchUp 8 or 2013, you won't be able to access the 3D Warehouse using the Get Models tool, or through the Components window. Though you can always download models from the 3D Warehouse website, then import them into your SketchUp model. If you use geolocation features, you won't have access to Google Earth features, including street view photos.
If you don't mind a bit of hacking, you can make manual changes to your sketchup.dat file, which will restore some functionality to older versions, once the "break" occurs on June 1. Instructions are here - they're not too complicated.
