BB Curve :: Error "Content Rights Do Not Match The Device"

I've got a blackberry curve 8530 (software version 5.0 Bundle 1675). My desktop software updated a few days ago (to 7.0.0.59).During synchronization of contacts, I get the error in the subject above.I have gone to the bb knowledge base here[URL] I have completely reset the device to factory defaults as described here - [URL].That much worked.I have restored from backup. Full backups. The restore completed successfully.Then I tried synchronization again. Failed again exactly as above. So I reset to factory defaults again and tried restoring from a different backup. Still failed in synchronization. I have also powered off and on. And removed the battery. Various combinations of all of the above. Before I throw this blackberry away and get something that works?My synch is attempting to synchronize only contact data. I have set it up only to try that. It's not trying to synchronize anything else. The contact data is being synchronized from my computer's contacts folder to the smartphone - one direction only. Computer contact list should always win. That's the configuration setting.I keep seeing this as well: "Content rights do not match the device. Please insert the media card back to the right device" (then an OK button below that). I have a media card all right, but I have not removed nor inserted it, nor changed it in any way.
