I was one of the winners of OA. Here's my feedback:

I installed the software with the emailed key ( also registered my online armor account ), after that the wizard started, but it seems that wizard didn't attend Hogwarts because it froze analyzing my start menu . After canceling it, I had to restart my computer to finish the installation. I did some tests to verify it was working correctly and everything seemed fine until I tried to check my email, I couldn't open that page or any other https page with any browser. Maybe it's because I have kaspesky internet security installed but with the firewall disabled (I didn't want to uninstall it because I have many days left from one of the chinese promotions), for now I uninstalled OA to check whether the https pages will open or not, I'm thinking about installing OA on another computer or maybe uninstall KIS to see if the problem persists, either way I'm surely going to use the license.
Thanks
