Cannot run ad-hoc iPhone app

I am trying to run a beta ad-hoc app on my iPhone for the first time (I am not a 开发者_如何学JAVAdeveloper and have no prior experience with this), and I cannot get it to launch. It shows up in iTunes fine, it transfers to my phone fine, but when I tap its icon it appears to launch, then immediately quits back to the home screen. I tried downloading the SDK and adding it through there, and it gave me this error message:

"The Info.plist for application at [redacted].app specifies a CFBundleExecutable of [redacted].app/[app name], which is not executable"

Sorry I can't be more specific, but this app is still under NDA. Anyway, if anyone knows how to fix this, please let me know soon. In case it matters, I am using an iPhone 3GS with 3.1.2 and iTunes 9.02. Thank you!

Never mind. It was just a permissions error. A simple chmod +x [AppName] command in Terminal is all it took to fix it.
