How can I solve a conflict between my newly-downloaded Aperture 3.4.3 and iPhoto 9.3 versions?
I downloaded Aperture 3.4.3 from the Apple App Store today. Now when I attempt to open my iPhoto 9.3 I receive the following error message: "To open your library with this version of iPhoto it first needs to be prepared." Then this second paragraph also appears: "You have opened this photo library with a newer version of iPhoto. Please quit and use the latest version of iPhoto." I'm not able to run an update because the iPhoto application won't open. Also, when I check for software updates I receive a message that my software is up to date. What gives? Have I missed a step in merging my iPhoto and Aperture libraries? I'd like to be able to use iPhoto again, because there are albums there that don't appear in Aperture.
Aperture 3, Mac OS X (10.7.5)
