mountain lion
nothing in my iWorks app opens. Upgraded from Lion, performed all the updates before doing so, and now nothing works. Pages and numbers open, but I cannot create new documents. Clicking on NEW does not create a new document. Clicking on "new from template" brings up a black window with nothing to select. I tried unistalling everything twice (and updating), but nothing. I use both programs for work everyday. I cannot live without them? Please HELP! Also, I cannot even open old files!!!!
