I found iWork09 online and started a trial version. I need to send it to someone with a Mac, but so far, they can't open it! I saved it and didn't change any settings. They couldn't open it. I click "get info" to see if it can help and see why. I then see its "Read" for staff and everyone else; so I change it to "Read & Write." She still can't open. What is going on? What do I need to do for it to work? I'm not tech savvy. Could it be because she is using another version of iWork? Thanks for your help.
