Navigator is designed to run all your ATP libraries, both Regulatory and Maintenance. Each library includes a license to access that libraries data. The "Not Licensed" message usually appears when you are trying to access content that is not in one of your libraries. For example accessing a heavy AD with only a light AD library, or accessing a maintenance SB or ASI (SB incorporated in an AD) without the needed maintenance or regulatory library. Email us at firstname.lastname@example.org or call 800-227-4610 with the exact example and we be more specific and get you the document needed.
