Glad your back home and safe!!!! I can't imagine the time difference and having to keep going today, I'd stay in bed all day to recoop from all the fun!!
My camera did that once and said that all the photos were gone, but I got a Photo Recovery Program that found all of them. If you need the information, let me know, b/c you don't need to spend a lot of money to find the photos.. but if its new I'd take it back and make them pay for the issue or recovering them!!!!!
