Photoshop Elements 11 won't roundtrip in Aperture
I just purchased Photoshop Elements 11, installed it, selected it in the Aperture preferences, restarted Aperture and tried to edit an Aperture photo using the new Photoshop Elements 11. From Apertures "photos" menu I selected edit with Photoshop Elements 11. Aperture created a new version and opened Photoshop Elements 11, but my photo file did not open in Photoshop Elements so could not edit it from Elements. Anyone else have the same problem? Ant suggestions appreciated.
MacBook Pro, OS X Mountain Lion (10.8.2), Aperture 3.4
