Yes there is. You need a card recovery program which should be able to recover anything the camera has recorded on to it. You can get free ones, but I suggest buying one (They're fairly cheap from about £20 or so)
What make is the card and where did you get it? If you say ebay, there are so many ringers being flogged on there. Don't ever buy cards on ebay. Alot are fakes, and when this kind of thing happens, you wish you'd got a decent one at a few extra pennies!
I think you can relax, I'm sure they'll recover just fine. I recovered photos from a holiday in Egypt some years ago, after my camera went for a swim in the sea!
Good luck, and let us know how you get on
Oh...and then get the pics up on here ;-)
