I've been playing with the Beta player for a while now, but I still use the Flash to view history. I've not been able to load the Flash player for about a week using either FF11.0 or IE8
Have you tried uninstalling Flash from Control Panel, closing all browser windows and then re installing from Adobe?
i'm pretty sure its not Flash itself. I can see it trying to load the image then it craps out and just gives me the header/footer for the player, tho the player bar is empty. that and flash is working on other sites.
ok, so i was wrong. updating it did help (at least for FF)...
