When I try to use the departures/arrivals search tool, into Miami, for a date within the acceptable date range, and keep getting the following error:

Error Requesting Data [R]:

Error 12057: Gopher - Attribute Not Found
Unable to validate the revocation of the SSL certificate because the revocation server is unavailable.
Disconnected (1s)

Error 9002: No Data Received
Disconnected

I have entered a valid FlightStats username/password and made sure that the default settings were still intact.

Any suggestions?
