How did you restore the catalog?
I think I copied and pasted the backed up catalog to my new computer, loaded up Lightroom and then from Lightroom did File>Open Catalog and navigated to the pasted file. I am using LR3 by the way, if that makes any difference.
Thanks for taking an interest
Well then I'm stumped, if the edits are present, and you really followed the method you just described, then the keywords should be there. You are saying that the Keywording Panel is empty (shows no keywords) for a photo that you were sure had keywords? Or are you deciding the keywords are missing via some other process?
I have discovered what the problem is, which is I am an idiot!
I had inadvertently clicked the smart collection "Without Keywords" which accounts for the fact that the photos that were on view had no keywords.
So problem solved. Thanks again for taking an interest.
