If you have a computer with a memory card reader that takes the stick. insert it into the computer and goto my computer find the memory stick drive letter and format it their then retry the stick in the camera. also try to go into the cameras menu and try formatting it their if you cannot format the stick it is very possible it is bad.

I am having the exact same problem and I have only had my camera for 2 weeks. We took it on vacation and I really want my pictures. Did you find a solution? Was it the memory card or ther camera?

I had the same problem, you can solve this by:
1. Push the card multiple times in/out the slot or
2. Use a little bit of contact spray on a small piece of tissue, rap this in the length around the memory card just 1 time. Be carefull not to make it to thick that it get stuck in the slot. Then push the card multiple times in/out the slot or
3. Cut a small strip of waterproof sanding paper (grain: 400 or more - the surface feels just like paper, and is just a thin as paper) just as wide as the card or slot. Cut a strip of plastic (eg.old credit card) also just as wide as the card or slot. Rap the sanding paper in the length of the strip and insert this in and out the slot. But!! ... make sure you stay at the upper side of the contacts, don't worry just do it carefully, don't use force and sand the contacts a couple of times. This way work for me, finally!!
