I just got a copy, with multiple licenses from work of Microsoft 2008, since my new MacBook Pro didn't have it...it only had the trial version. I Installed it the other day, but every time I click to open anything up, it comes up with the free trial version and asks me to put in a product key, or buy one. Does anyone know what this means? Forgive me, but I'm not a big computer person, so I'm a little lost. Thanks for any help.
