The server launcher states that the server is "undefined". I have tried reopening/restarting but the problem still persists.
I've seen unavailable, but not undefined. Just for clarity, do you mind pressing command+shift+4, then press space, then click on the window to take a screenshot, and post it here?
Have you tried repairing your client?
type ''thereisnourflevel'' when the patcher is selected.
