The best place for this is in the help forum I am sure the Moderator can move it at some point, but yes the crash probably done it. It not really a good idea to ever connect you camera to the computer, even though I have been guilty of it. Crashes like that can damage memory cards and I have read about it damaging cameras too.
Instead get a cheap card reader and use that. I would reformat the card and give it another go. Just to see if your card is still good. The images on it now are probably toast.
