Thanks for helping me, I will explain in more detail. My latest lightroom 4 version crashed and didn't want to reopen any more. I opened the backup version of february 2013. In this version my most recent added files, for instance family.march2013-file, were not there any more. But if I open the import field and try to import a new photo, I have a choice for import-destinations (on the right side of te screen). The files that are shown to help me pointing out where the new photo needs to go to do show my latest "family.march2013" file.
So I thought, maybe I can get them back although I do not have a very recent backup version of my lightroom catalogue. Is this a sufficient description of my problem?
thanks any way,
Arine
