Hard to believe it's only been a year since I first started blogging... so much has happened. It's really great that we went out so early with the news of the file format change, we started talking about it an entire year before we shipped a public beta. I think that helped to get a lot of the questions answered ahead of time, which is really important.
Speaking of the Beta, you may have noticed that the servers are really bogged down right now. A number of folks have had trouble getting the product keys. We are definitely aware of the problem, and there are a lot of people out here working to up the capacity. Sorry for the inconvenience.
