Why are certain views or editors not available?
NaturalONE makes use of a licensing mechanism. If the license has expired or no license file is found, some NaturalONE functionality is disabled. This affects in particular the source editor, the DDM editor and the Natural Server view. The path to the license file is defined in the Natural preferences. See Installation in Setting the Preferences, which is part of the Using NaturalONE documentation.
