Want movie to loop

I have created a small flash movie for a banner add.

It consists of about 8 Movie Clips.

Each MC has it’s own onClipEvent (enterFrame) actions.

Each MC is on it’s own layer.

The movie only has 1 frame, with getTimer() function used.

My problem is I cannot get my MC to loop, when finished movie.

It is as if the movie doesn’t end!!

Am I not killing these processes or something
