Freezes on splash screen. This is horrible.

When I run an app, ANY Titanium app, in the debugger, it works fine on both IOS and Android simulators. When I run WITHOUT the debugger on either simulator, it hangs at the splash screen. If I deploy it to the device and run it, it hangs at the splash screen.

If I load the xcode project and run on the simulator in xcode it hangs on the splash screen. I see the message:

[ERROR] Error connecting to debugger: Error Domain=NSPOSIXErrorDomain Code=61 "The operation couldn’t be completed. Connection refused"

I'm using the lastest version of Titanium (3.1.0GA), XCode 4.6.2, IOS 6.1. Android 4.2.2, and earlier versions show the same result.

I've tried disabling analytics, disabling all breakpoints, cleaning, rebooting, etc. I don't even know what else to try or where to look.

Any help?
