When you imported the toolkit the first time, you should have seen a log of what was imported and it should have listed several items. If you only see one line, then I suspect the install did not proceed correctly. To re-import the toolkit, open regedit on the collector and browse to HKLM\SOFTWARE\Wow6432Node\Configuresoft\ContentUpdateService. Locate the string value key for the toolkit you need to re-import and delete it. Launch the Content Wizard (make sure you're running it with an account that has SA rights into the VCM DB) and you should now see the toolkit for importing. As a sanity check, restart your VCM web session.
