PocketPedia will not install on iPhone

[spj]

I downloaded Pocketpedia, but it refuses to install on my iPhone. When I synch, I get a message that says:

The application "Pocketpedia" was not installed on the iPhone ____ because you are not authorized for it on this computer.

What gives? I am a registered (i.e., paid) user of all three Pedia apps on my Mac. Does anyone know what the problem might be?

Thanks for any help anyone has to offer,

Sounds like a permissions issue between your iPhone and your iTunes account. I would do a restore of your iPhone OS software.

"Authorize computer..." under the Store menu in iTunes is also worth a try. You can also look download and install Pocketpedia directly from the App Store on your iPhone or iPod.
