LR 3.6 has worked OK before, but now stopped importing photos (jpeg and raw) from my cameras (Canon 5D Mk 3, Canon Powershot 100). Program goes to "does not answer" - status and must be closed. The problem seems to be similar in my Elements 8. Importing from my Canon G10, LR says that there is not preview available, but importing succeeds. All cameras import photos to Windows (7) or Picasa normally.

People seem to have problems importing directly from Canon cameras. Try using a card reader instead. Or perhaps you could use Explorer or Finder to copy to the hard drive and import from there.
Thanks. Importing from a card reader or from the camera works in Windows. Is seems to work also from the card reader in LR. LR recognizes all the cameras, but photos only from G10 and without previews.
The camera brand cannot be the explanation, because importing has worked OK before this (for years in LR 2). I am reluctant to accept, that I cannot import photos to LR directly from the camera.
Is it possible, that some importing settings are in wrong position or somehow corrupted?
