IE not playing Java Games

I noticed that when I went to play the Java games on my Original Game Room with IE they did not work. If you go to Tools-Manage Add ons and then click the Toolbars and Extension button-then Enable Sun Microsystems, Incs: Web Browser Applet Control and Java Plugin. There was another Sun Microsystems which was (not Verified) the JQSIEStartDectorImpl Class, I made sure that was enabled also. They should now work, had no problems with Firefox.
