Hmmmm, I guess it's possible Ritzy - especially if your photo program was putting temporary files on the card or has "locked" the card for some reason. E.g., when I open a photo (in RAW format) from my card in Photoshop, it writes a separate file to the card that (I think) keeps track of the settings I used to "develop" the RAW file. (If that doesn't make sense - don't worry about it. I don't go into RAW files in the videos - it 's a much more advanced topic!) But the bottom line is that Photoshop DOES write a file to my card if I open the photo on the card before copying it to my hard drive. And if I try to "safely remove hardware" while Photoshop is still running (even if I've closed the photo), I'll get an error that "the device is currently in use" and I need to close Photoshop before I can "safely remove hardware". Sooooo - it's possible that you pulled the card out while your editing program had it "locked" and that caused problems.
That said, the biggest problem that I've seen is that the files on the card get corrupted - not programs getting messed up. Have you tried uninstalling and reinstalling your photo program?
