Does anyone know how to make this work?? It won't let me save or print. I'm getting mad.

I have installed, uninstalled installed and uninstalled until I want to scream. It sometimes will not open, and every time when it does open, I cannot print or save my work. It says the 30 day trial has not been activated. This is the Install DVD, never opened, except by me, on this only computer. I have updated and everything. No good. What the heck?????
