This morning I followed the ELC instructor into the lab to make sure everything was working, and experienced the same problems as before: Starting the teacher program results in an RSRV error. This happens even after confirming that RSRV.exe and RSRVAny.exe are running. The only thing that fixes it is to turn the console off and back on again before starting the teacher program. This suggests it's something to do with the sequence of events; the sequence that works is to start RSRV, then power up the console, then start the teacher station.
The station is also lacking any obvious links to the teaching materials. I was able to navigate easily to them, but it would be hard for a teacher. In the past, we've put a link to the materials folder in the actual directory in which the teacher station always opens up its dialog box (which if I remember rightly is somewhere in its program folder). I'll do that if I get a chance today.
