Update 3.5.3 not working (from 3.5.2) MacBook Air 10.10.3
App store told me updates were available for Pages, Keynote & Numbers. Pages and Keynote updated fine. Numbers kept giving me errors. Now the App store doesn't even acknowledge there's an update to be made. I have 52 GB of space available.
MacBook Air (11-inch Mid 2013), OS X Yosemite (10.10.3)
