Cannot update keynote "since you have not owned a major version of this software".
I ordered my Macbook Air with keynote together online, so keynote does not appear on my purchase list. Hence when I try to update keynote, it keeps saying that "you cannot update this software since you have not owned a major version of this software". Any help is appreciated, thanks!
MacBook Air (11-inch, Mid 2012), OS X Mountain Lion (10.8.3)
