Mine wouldn't connect to the PC via USB. Windows 7 said it had finished installing the drivers. Then the camera would try to connect, opening a dialog, and then immediately closing it, bouncing like a ping pong ball. Tried all the usual. Restarted PC, looked for drivers on Samsung website, nothing. Tried my usb on a different camera, cord worked on that one so I knew the cord was fine.

Photos I took today will not upload to my computer. This never happened before. What is wrong?

I cannot upload my photos from the Samsung WB200F.
