Sounds like the card has become corrupted. Take no more pics until you've recovered the photos, take the card out of the camera. Here's some freeware photo recovery software that should be what you're looking for:

You will need to use a flash card reader with this software. Also, highly recommend that you consider using a card reader to download your pictures in the future. You insert the camera's memory card into the reader, and then insert the reader into a USB port on your computer. The card then shows up as a hard drive so that you can simply copy/paste or drag your picture files onto your computer. Card readers are much more faster in downloading pics, do not require the use of your camera's batteries, and provide much more reliable downloading of the pictures (fewer errors). They're also VERY inexpensive these days. Here are some examples from Amazon for your CF card:

And finally, recommend formatting your card in your camera only AFTER you've recovered your photos (this will erase the card). This should fix the card for future use. Turn on the camera, select menu, then select the tools menu. Scroll down to the selection outlining your's cards memory capacity and select it. Then follow the formatting prompts.

I'd recommend that you follow this digital camera photo recovery guide as soon as possible to recover those pictures.
