Cisco discontinued support for these devices back at the end of 2013 - see the End of Life and Support Notification.
A quick search of google shows that there are many people who have had similar issues with them not working.
If you want to try to get it to work, try some of the suggested things that can be found on a google search - this one for example: how-to-troubleshoot-common-flip-video-problems.html
Given they're such an old and unsupported device, I'd suggest you look at purchasing a new device that is supportable.
