Aperture 3.4 will not open.
Upgraded t Mountain Lion 8.2, iphoto 9.4 and aperture 3.4. iphoyois fine. When trying to open aperture it opens to my iphoto library (which I want) for a fraction of a second and then quits immediately. Rebooted and still with problem. Any ideas? Should I reinstall 3.01 and then upgrade again. If so how do I delete all of the version on my computer?
Is there a file I should delete??
By the way this is on a relatively new iMac.
Thanks in advance to all who can help/
iMac, Mac OS X (10.7)
