IE Trouble

When I used Replay Media Catcher to launch my IE, I got an information bar that stated: " Internet Explorer is currently running with add-ons disabled", and then when I tried to see a video I have an error that states: "Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player.". I have tried to go into Tools\Internet Options\ Adavanced\Settings to look for and enable JavaScript but Java is not in the settings. How can I get around this issue? I have the demo copy, but the program is currently useless and does not do as advertised!!!!!
