Aspen Simulator not working

I have googled for two days and still no luck. I am running a Mac OS X 10.5.5 and the iPhone SDK 3.1 beta, running the Aspen Simulator.

My problem is that I can not get any app to work on the Simulator. It builds alright but the simulator shows a black screen and then returns to the main menu. I get this error on Xcode:

Error from Debugger: Failed to launch simulated application. See console.

and in console,开发者_Go百科 it says something about "unable to find springboard (bootstrap lookup error".

Can you please help me?

I think you should think about updating your system. Using an old iPhone SDK 3.1 beta nowadays is really strange, you should update to the latest stable iOS SDK 4.3.3 and test backwards compatibility of your app using the built in iOS SDK 3.2 from iPad. This will help you test the app on this older SDK while getting active support from both Apple and developers.

Tell me if updating solves your issues or not. Thank you!
