My DVD was bad. The install started and died after about 5 minutes. Fortunately it didn't corrupt anything. Unfortunately I had to sit on the phone for about 30 minutes explaining the problem and getting them to send a replacement. Now I have to wait for that to show up. If I hadn't been eligible for the $10 upgrade I would have been pissed that I paid the full $30 when most stores are selling it for $25.
