So I'm in the The Barheim Passage and nobody seems to be able to do ANYTHING except for Fran. Vaan's Magicke's are turned off so I can't use my Cure, Fire, Thunder, etc. His MP is constantly at zero (wtf? How did that happen??)

Did I push a button accidentally somewhere that makes Vaan's MP stay constantly at zero? And why, when I click on "Magicke's" for Baltier does it show everything blacked out even though his list shows he has Green Magic, White Magic, Black Magic, etc???

What did I do?
