Glad that at least has your workflow going. Yeah the email notification it is something that required for workflow really, but it isn't too far away if you look at the Sitefinity Road Map
page you will see that it is slated in for version 3.2, which I think I saw somewhere is coming out early next year which isn't too far away, so something for your users to look forward to.
On that note Telerik, I have a feature request, when looking at the Email notifications do you think it would also be possible to consider an RSS feed to be able to pull a list of pages that need to be dealt with by a user.
Sorry I can't be of much help with the Sitefinity licensing issue, I am on an older licensing scheme. I would imagine that it has something to do with either the way the license has been generated, are you sure the IP address that you are accessing the site on matches what you generated?
