I've just installed LR5.6 and it seems to have lost my images, with a "file not found message.
The files are all still there (checked with explorer but lightroom had decided that it's looking for files with the old filename but with a -2 suffix appended. This has happened with the two PCs that I use.
Not all files are affected.
Why has lightroom decided that the file names have changed and how can I reverse this?
I stress that this is an issue that has appeared only when I've updated from LR5.5 to 5.6.
