Mike,
The first error relates to the portfolio export function, and looks like something I should fix. But I think it is not the problem you are having. The second error is occurring because there is no file to display. I think that is caused because your camera is not being picked up and the recorder is recording, but recording nothing. That still doesn't explain why only "feedback" is giving the problem.
Before you commence recording, try checking both the device settings on the recorders settings tab, and the webcam settings on the flash properties page (right click the recorder). Can you select the webcam on either of those locations and cause the webcam light to light up?
