Can anyone help?

I'm so angry.

I cannot move Zidane (who you cannot even see). The cursor on the map is there, but he will not walk, it's as if he's trapped.

His cursor on the map is very close to the airship's cursor.

Disc 4, island near chocobo lagoon.

Can someone help, and if not, can I email PSN? Not sure where to find their contact details.
