I have an application/game i am trying to create at the moment, that when release it will be continuly updated. New characters new items and so on. This application will be installed on the users computer and have its own directory full of swfs dynamically loaded into the game. Now instead of making the user download update installers everytime a new character comes out i was wondering how i would go about getting flash to download things like that in a update screen before the game starts. I have seen this in a current flash game called dofus before so im pretty sure its possible. I just cant work out how to make it possible.

Its pretty crucial i work out how to do this now before i make any more progress on the app/game.

Any help or advice would be much appretiated thanks
