Document Camera and Face Camera

HI Peli or any other super stars out there
My document Camera seems to replicating my face Camera, I have cleared the cache on my computer and tried all the other options available for us to use, is there any way to reset the streamer so it has no memory of the devices?
Any suggestions would be awesome - WE LOVE STREAMER and use ti in conjunction with Classroom for our online live streaming club!
