Everything was going smoothly until..... (flvplayer issue)

Put together a video spot, using the flvPlayer component, everything was running fine, until I copied the two frames I was using, and placed them in the site I needed them.

No video.

................ I'm a bit crosseyed at the moment after a day's flashing, but am I missing something obvious here?

My thoughts are currently thinking that the component in the "work" arena was on the first frame, and for some reason didn't like being copy and pasted into frame 52 of the "real" movie.
