Do you have the extension checked on?

In desktop, under the Customize Toolbar, Select Extensions and make sure it us checked.  ArcMap and ArcCatalog act independently, so you will need to check it in which ever software you are using at the time.  Since all the extensions come with home use, if it was me, I would just check them all on.
