BOC Images: Error: String was not recognized as a valid DateTime

If you receive the error
"String was not recognized as a valid DateTime"
it is because the client is unable to connect to the BOC TAPI Connector to validate its license.
If all operators are affected, reboot the BOC TAPI Connector server.  Wait 10 minutes and ensure all of the BOC Services are started and then retest.
If it is a single station, with other operators able to work, it is a configuration issue.
Verify that the correct server is listed in the workstation registry key
