Update: So tech support finally figured out a solution: re-registering the eDGe. Re-registering proved a bit tricky for me because my original password was not alphanumeric, but once I got over that hurdle by changing the password (which didn't prove simple), the registration process took a couple of seconds and the enTourage homepage loaded immediately. At one point, I was advised to backup all the content and reset the eDGe to factory settings, which I didn't do. Before any of you try that, try re-registering.
