Trying to finish the "Visualforce Basics" trail and I think I'm encountering a system error rather than a "me" error.

When I check the challenge I get this error: "No Apex class named 'NewCaseListController' was found" (http://screencast.com/t/AeGb37gjnod)

But I definitely created the class, it's definitely named 'NewCaseListController', and the page I wrote is definitely working correctly:
http://screencast.com/t/XJ1CjjYebwv and http://screencast.com/t/10aDrf5Vu

Can anyone else's eyeballs spot something I've done wrong here? I also tried logging out of everything completely and reconnecting, but still no luck...
