Both "Save As..." and Duplicate are missing from file menu
Just upgraded and am running OS X 10.8.2 and Keynote 5.3... The file menu has only Close, Save, Revert to Saved, Export in that section. Pressing the option key doesn't change duplicate to Save As... since Duplicate is missing as well. When I press shift-command-S i get an error sound and option-shift-command-S does nothing... Every other mac app is working fine. Obviously, I need some help.
MacBook, OS X Mountain Lion (10.8.2)
