I am a professional presenter and rely heavily on Keynote. I purchased a new Macbook pro (and RUE THE DAY). Lion has caused me endless problems. I have just come off holiday and try to give a presentation using keynote (09) and lo and behold
KEYNOTE cannot be opened because of a problem ...bla bla, check with developer to make sure keynote works with this version..bla bla... be sure to install any available updates bla bla.
I'm running Lion 10.7.2. I reinstalled IWORK 09 with the keynote upgrade patch from Apple. No progress. I am frantic. Any help available??
