NoahCfgDatabase.sdf is not configured correctly when Restoring a database from another computer or from an older version of Noah 4
After using Restore to bring in a Noah 4 database from another computer you are presented with a blank screen when launching Noah 4:

Solution
The database that holds configuration settings for Noah 4 has been improperly restored. To resolve the issue you can rename the NoahCfgDatabase.sdf file to NoahCfgDatabase.old to create a new file. Preference settings like module order and customized fields will need to be reset:
- Navigate to Services and stop both the Noah Server and Noah Client services, then minimize the Services window.
- Navigate to the NoahCfgDatabase.sdf file located at Program Files/Common Files/HIMSA Shared and rename the file to NoahCfgDatabase.old
- Restart the Noah Server and then the Noah Client services.
- Launch Noah.
Or if you wish to retain the preference settings in the configuration file you can manually move the NoahCfgDatabase.sdf from the backup files:
- Navigate to Services and stop both the Noah Server and Noah Client services, then minimize the Services window.
- Navigate to the NoahCfgDatabase.sdf file located at Program Files/Common Files/HIMSA Shared and rename the file to NoahCfgDatabase.old
- Copy the NoahCfgDatabase.sdf from the backup files to Program Files/Common Files/HIMSA Shared
- Restart the Noah Server and then the Noah Client services.
- Launch Noah.
This issue will be addressed in the next release of Noah 4
