I was out of town and let my monthly license lapse, since I wouldn't be using it for 3 weeks. I've just renewed it, and the license manager tool says everything is up to date, and it's downloaded to my computer, but when I try to open my projects, the program says that my license update was unsuccessful. I did "downgrade" to solo this month, as I have no need for teamwork, etc. Is that my problem? If so, any suggestions for how to get things running again?
