Createmptymovieclip problem

Hallo guys!

The problem that I am having is that after I load an external swf file in the container I created using AS the lower swf retains its functionality and it is not replaced. It should have been replaced cause I loaded the movie on level 0. But even if I try to load it to a different level the problem remains. The buttons of the “main” file remain active. Lockroot did not save me and I am trying to find a different way of killing the first swf.

Any ideas?
