Microsoft Office Professional 2007 trouble activating??

Okay so I downloaded the trial and it expired. Then this screen came up:

I entered the Product Key it asked me to enter and then I clicked next and got this screen:

So after I clicked install, it completed successfully and I got this screen:

So I did what it told me; restarted Microsoft Office and then THIS came up:

...again, I know!

What the hell am I doing wrong? I really need this thing to be activated and I have the rite product key but this thing keeps going back the way it was. It also says how I will be prompted to activate, but I already did!
