Container // External .swf help

Please can a flash expert help me with this.

I have started creating a flash site which consists on a main movie which load other movies into a container.

I have made the first 2 buttons active:

  1. EVENTS - when clicked this opens the events.swf into the container movie clip.

  2. BAR - when clicked this opens the bar.swf into the container movie clip.

These buttons work fine when first clicked, however when i go to press the buttons for a second time, they refuse to open the .swf’s again?

Please can someone help … i am starting to panic.

I can supply the main.fla is needed.
