App store won't let me buy
I am using the trial version of aperture. I want to purchase the app, but when the box opens upon launching the trial version, I click "buy," and then I'm not able to do so.
Aperture 3, Mac OS X (10.7.2)
If you have the trial version and want to purchase Aperture from the App Store you need to first delete the trial version.
In the Applications folder drag Aperture to the trash. Any libraries you created during the trail period will still be useable from the bought version of Aperture.
