app build wont run on device?

I am trying to test my app on my droid phone, i have done a build before that had worked for me, but now when i build, it says it was created just fine, but when i go to install my app the progress bar never fills and it just says “app was installed” when i go to run it i just get a blank screen… any idea why this would be? also i am using the director class now in my app, could this be the problem?
