I bought a computer from best buy

Was it an introductory or trial software?

If it wasn't I would definitely make a fuss with Best Buy, I don't see why they wouldn't just pull a new software off the shelf and give it to you especially if you bought a complete system from them. I would do a screen print showing that the software is not working. First, make sure you haven't disabled it, and it is truly not functioning, BUT let them resolve it their own way first.
