At this point in time, I consider my tickets to be part of my annual donation. Sometimes I make the games, most of the time I don't. I wonder if the Athletic Department would just prefer a check equal to the amount I pay for tickets and parking?
Are you running antivirus on the new machine? If you are, checkout the firewall setting. It may be too restrictive, maybe set to Public. Change to Home/Private and see it that helps.
