Like the others said, battery dead and certificate gone. We get 2-3 calls a month reporting this error message, and that's always the cause of it.
Contact the vendor who sold you the SX-3000, who will arrange for its return to GDC and its replacement. If it's still within warranty, there won't be any charge (apart from shipping). If it isn't, you'll need to extend the warranty, and I'm afraid that you'll need to be prepared to write an unpleasant check.
Once you have the replacement, you may need the media block's public key certificate in order to have KDMs issued for it. Deluxe Technicolor should only need the serial number, but if you play encrypted DCPs from any of the smaller distributors, they will likely need the actual cert (.pem file) from you. To get it, write to cert[at]gdc-tech.com with the serial number of the new IMB, and their typical turnaround time is 12-24 hours.
Once you have the new IMB, I would strongly suggest that you include battery replacement as part of your planned maintenance routine. If your theater has a multiplex usage pattern (IMB powered up 10-12 hours a day, seven days a week), I'd suggest every two years, but if the IMB is powered up for significantly fewer hours than that a week, I'd suggest annually. GDC sells a battery replacement kit, available through your vendor.

In one of those weird coincidences, I was asked to install a used SX-3000 into an NC900-A this morning, and check and verify proper working order of the projector and IMB in preparation for shipping it to a rental customer. The IMB had been on the shelf for about a month, I was told, and before then it was in regular use (though we don't know for how many hours a week).
Anyway, that one was toast, too, for the same reason. No SM light on the front panel, error connecting to Security Manager, wouldn't marry to the projector, goodbye and goodnight. That one will have to go back to GDC for a new battery and certificate, too.
The moral of the story is, I guess, that IMB certificate battery swapouts need to be included in every theater's planned maintenance routine.
