Without physically looking at your computer it would be impossible to say why you weren't able to watch a movie on this computer, and if you want a Geek Squad® technician to look at your computer you could call 1-800-GeekSquad.
With that being said if you are prompted by a popup window advising you to download the latest version of Adobe Flash Player, when trying to play this movie, I would suggest downloading this program from Adobe's website (and of course installing it). You can download the latest version of Adobe Flash Player here:
