I have my CF cards for many years, no failures at all. Get a magnifying glass and a decent lamp, look as best you can into the 50 sockets and try to see if there is broken pin still in one of the socket holes, or a piece of fluff.

Insert the card into the camera, are the images readable?
If all is well, buy a card reader, not expensive.
