Hello, Lee
I am also having difficulty viewing the tutorials. I tried your suggestions and lowered security, and changed browsers. I also changed computers and still have the same blank screen.
When I right-click on the screen, I see 2 messages ... "movie not loaded" and "about Adobe Flash Player 10". The movie not loaded is grayed out.
I can see the tutorials you sent in wmv, but not the htm. Can you help with this?
