Hi:
Try renaming the card.
BTW I have T5, T2, LD and TX. Think about the TX. The LD is heavier, slower and bug prone. While the T2 is great, it lacks some features v LD. The TX has an SD slot, mine has a 2gig card. It is lite, better battery life, much faster, BUT still has some bugs. It is worth $300.
Good luck
Bill
