I got a Flip Ultra Series about 20 days ago. It worked perfectly and everything was good I loved the camcorder. And just today I tryed pluging it into my Windows XP computer. The screen turned on and I heard the Camcorder turn on. The computer did not recongnize it and then I heard the Camcorder shut off. I took the camcorder out and the same thing happened. A mesage popped up on my computer saying something about unknown device. The camcorder just turned on and off and on and off. I took the camcorder out of the PC and then turned the camcorder on and it said usb conected when it was not even plugged into the PC. This is the error I dont know if I should return it or if it is fixable. Please help me this is confusing me.
