creating universal app using flash cs5

Hi,

I'm using Flash CS5 and I wanted to create an universal app (iphone + ipad).

Then I click the "iphone IOS settings"  there is no device menu, so I can't choose the desired devices..
I dont know why the device menu has disappeared?

I saw on several video tutorials, that you can simply choose the desired device.
But then I look at my own project and I click the "iphone IOS settings", I cant find any "device" menu by the "general" tab.

Does anybody know how I can resolve that problem?
