Its easy to determine if you have a bent pin, just take a small flashlight and look into the slot the cf card fits in. If you have a slightly bent pin and haven't used too much force trying to insert the card you may be able to straighten it with a small vascular clamp you can get at Radio Shack. Make sure you remove the battery and let the camer sit turned on for 24 hours before you try to straighten it, not because of a shock hazard but to keep from shorting out the cf connector. Don't use a lot of force and don't bend it back and forth or it will break. If its beent completely over then don't try fixing it just send it in.
