If your navajo workspace gets corrupted, you can always just delete / move the workspace, and you will return the installer, so you can recreate a working Navajo installation.
Alternatively, if you want to update a to a new version of the Navajo Framework, you can simply delete the Navajo.war file, and replace it with a new one. All content in your Navajo Workspace will remain unchanged.
