Connection to database could not be established about importer-exporter HOT 6 CLOSED

Go to "Preferences -> General -> Logging" and choose DEBUG as log level for the console. Afterwards, try and connect to the database again. The console window should then contain a stack trace of the connection error.

It seems your 3DCityDB database instance is not set up correctly. At least the function citydb_version() in the schema citydb_pkg cannot be correctly executed. Have you followed the steps in the manual when setting up the 3DCityDB?
