Anybody pls help

Hi all!

Iam designing a site in flash. It has 11 scenes and was working fine. But today it is showing an error message as “error Creating flash movie. there was not enough memory” when Ctrl+enter is pressed. Pls explain, how to rectify it?
Can you pls explain how to add music to a flash file? I have added music to a scene. It is working for that scene only. But I need the same background music for the whole flash file. So pls help me out with this.

Thanks in Advance
