Aperture won't open or update
I get a message that the iPhoto library cannot be opened when trying to open Aperture and it says I need to update Aperture, but there are no updates available. I am using OSX 10.9.2. I am not computer savy and do not know how to resolve this. Is someone able to assist me in fixing this? Thanks
MacBook Pro, Mac OS X (10.6.8)
