“security policy error” on iPhone and iPod Touch

Question

I'm getting an "Error from Debugger: Error launching remote program: security policy error" when I try to run my app on my ipod touch. The provisions look in order, and the app builds to my iphone 3gs just fine. The app used to build just fine to my ipod touch, so I'm flustered what could have changed and wondering if anyone has any thoughts on what might be causing this issue. The build logs are below.

Answer 1

We "fixed" this by installing the release version (built for ad-hoc distribution) and then debugging from Xcode. It installs and updates the application fine from now. 3GS with 4.3.2.

Answer 2

Delete all old expire provisioning profile..

Answer 3

Have you checked that the iPod doesn't contain any expired provisioning profiles? I've had trouble in the past when building to devices that contain expired provisioning profiles.

Try removing any expired profiles and see if it helps.
