Thumbs down NoSuchMethodException - 11-07-2013, 10:20 AM

I have a student who after several hours working on his program, tried to reopen it only to receive the error below. Is there any way to recover from this, and get his project at least editable? (another computer definitely didn't solve the problem) Any ideas what causes these problems, so I can tell students what to avoid in the future?
