When launching NBS Contract Administrator the following error message is displayed:

"An error has occurred. This could be due to NBS Contract Administrator attempting to open an invalid database".

 Invalid Datastore error


This error can occur if you do not have appropriate permissions to the data store file, (CAFtab.cadb).


Please contact your system administrator to check that permissions on the CAFtab.cadb file are set correctly.

To view the system permissions on CAFtab.cadb:
  • Right click on the CAFtab.cadb file in Windows Explorer and then select Properties.
  • Click on the Security tab.
  • Make sure the permissions are set to Full Control.
  • Click Apply and try loading the software again.

If you do have the appropriate permissions, your data store could be corrupted and you will need to contact NBS Software Support on 0345 456 9594.
