Hi there, Could anyone please help me with what is probably a simple thing, but which I can't get to work. I want to see the training videos in CFS3, and can find the relevant page where they are, but nothing runs when I get there. I've tried clicking on the 'stop' icon (which changes into a 'run' icon), and vice versa, but with no luck. Any help would be much appreciated. Many thanks. Stanier.
