First and foremost (for future reference)- STOP doing anything with the card right away. If there are issues and you are playing with the card it can make the items harder to recover.
Second, what system are you using, how are you trying to transfer the photos, how was the card formatted?
Did you get feedback that the pictures were captured properly?
You may need to try software like this

But it may be a bit late since you reformatted so it sounds like you may need to rely on the DVD ( if I understand your post correctly?)
