I just recently purchased a new scandisk 8gb duo pro card from amazon (a new one, not used). When i insert it into my camera and turn the camera on, everything seems to be fine. Then I take a picture, and the picture freezes on the screen for like 2-3 minutes. Then when i go to review the picture, nothing is there. Any ideas on what the problem could be?

Thanks

I bought this cause I am taking a trip real soon here and plan on taking a ton pics

Thanks again
Jeff
