OK, I'm confused. I don't understand how Office 2010 does license authorizations. I installed Office 2010 on a system and all seemed well, but then the user started getting a screen that asked for a license code. When I got to the machine I entered the 5 x 5 code that was on the back of the CD, but I got an error message saying that the code was invalid. So... Does Office 2010 bind however many licenses you bought to a particular 5 x 5 code? If you decide you need more licenses, do they get added to the original 5 x 5 code? The user who has this pop up is one of my first 2010 users, and really can't afford to not have Office running this weekend. How long does this crabbing message get displayed before Office stops working completely? Thanks! --STeve Andre'
