you should still have the download link, try re-downloading and installing again, sometimes the files get corrupted during the download process. If you have trouble fiding the link to the download go to the Vivitar site and find the download area and enter your model number, you can redownload from there.

Ebay has replacement battery and recharger kit starting at $14.00 bucks. Good luck!

Hi! go to this link so they can send you the software.

Hope this helps..

use class 10 card

your battery pack is probly out off,try one you no is good and try it if not that let it now,its could be a battery contact fail ...

Possible Solution for this problem. The battery might not be making contact with the terminals in the camera case. Open the battery door of the camera. There is a small spring "tab" on the other side of the battery door. Bend this "UP" a little, close the door and try it again. You may have to bend it up some more it it didn't work. By bending this tab up, you are forcing the battery UP to make better contact with the terminals.

Try the manufacturer: http://vivitar.com/products#Digital Video Recorders/2/31/Support
