This error was encountered because the default printer was not correctly configured in the Menu_Operations_Parameters table. This parameter must be configured correctly to allow the username creation code to successfully create the FTP folder and assign permissions. Any partially created username resulting from this error must be dropped and recreated to finish the process. 

If you require assistance to correctly configure the default printer and/or to recreate a partially created user, please create a Support request at, providing the details of the issue and referencing this solution.
