The weirdest thing... I was ok 2 days ago--I don't believe i did an update, in 5.5, but there may have been. Now, LR5.5 will not read my SD cards. It see's the pictures, loads them up into the import window, but races thru the import with a "cannot be read" error 33 message. I have done a workaround by importing into LR 4. 5.5 See's the photos fine, but my filing system in LR is obviously all messed up now unless I add folders into 5.5 from other locations.
