web camera stops sending

I have a web camera from x10.com that sends it’s picture to my web page. This is set up to send a picture every 10 minutes, and my web page shows the picture. Everything works fine for a little while and then stops. I have to close my web camera program and start it again. I have looked on the x10.com web site for help and found nothing. I need this camera to work, Why is this happening? And how do I fix it?
