We got a new computer recently, a Dell. The scenario worked great on the old computer, however it was a previous version of both the scenario and Aleph One (from April 2010, I think). I transferred them over to the new Dell using Google Drive, and they didn't work, so I downloaded the latest versions, and then the problem started.
I'll check the forums to see if there's any other ideas I can find.
