Luckily, I performed a back-up, 2 days before (to my external hard drive) my computer was infected. The problem is, when I try to use my back-up catalog I cannot get access to my development settings in the pictures. Everything is at zero.
Did you took a backup from Lightroom or are you referring to System backup?
Check the location Pictures>>Lightroom and try openign other catalogs too.
Also, Which version of Lightroom are you using?
Thank you for your reply! I took a back-up of the Lightroom catalog not a system back-up. The regulary when you exit lightroom. This back-up goes to an external hardrive catalog. But when I try to use this I cannot access the settings. I don't have any Lr catalog on my local hardrive. Because of the virus I was forced to delete everything. But still..It's strange that I cannot get access to the editing settings and that it shows my exported JPG files in Lr..
Sorry, forgot to answer. I use the newest Version of Lr, 5.6
Could you try opening other backup catalogs(recent) from your External drive.
It is possible that the virus infected the backup too.
Search your External drive for catalogs. Search for " *.lrcat " and see if it returns more catalogs.
I use the newest Version of Lr, 5.6
Latest Lightroom 5 version is 5.7.1. See Keeping Lightroom Up-to-Date
Thanks a million Akash!
I tried your proposal and manage to find a catalog that I could use and every settings is back on track now
Regarding Lr Version 5,,Okey, maybe I need to upgrade:-)
All the best,
