I have updated our license/serial number of the NFR copy of all Adagio modules. All modules work fine except in Inventory & Invoicing I am getting this error message:

"Error in serial number or install code (3), unable to continue. Reinstall the product and enter the serial number and install code from the product label that came with the Adagio CD."

When I click "OK" to the message it comes up again and if I click "OK" again then the login screen appears and I can open and work in the file.
I have reinstalled the modules but it doesn't make any difference.
