I placed my CF card in my Dynex card reader, then plugged the card reader in the USB port on my Windows 8 laptop. I had not used the card reader with the laptop, so it started downloading drivers. The pictures on the card were fine when I viewed them in my camera. Now the computer says the card is corrupt. I purchased Media Recover software and the software was able to find and restore the files from the card to my computer. However the files are file type CR2 and I cannot get Lightroom or Photoshop, or Canon Utilities software to open them. Has anyone had this problem and found a solution?
