Please show us a screen capture of the problem.
You may have accidentally opened a new/different catalog file, try the command File->Open Recent and select each catalog listed there to see if you can find the one with your photos.
Please explain this more clearly and in a lot more detail:
The new header when I open up LR. is ( Photos of Africa and date) I checked for my hard drive and it says (not saved).
In particular, explain what you are referring to by the word "it" when you say "it says", and please give the complete message, not just two words.
I'm so happy! I did what you suggested by Opening file and clicking on recent.
Everything came back on as usual. I haven't yet tried to upload anything to flickr.
I thought I lost everything!
Can you explain what the error for semi-colon expected means?
Thank you so much, I hope this can help someone else as well.
I don't know what the semi-colon message means, however I do believe that this has been solved elsewhere in this forum, so you should search for it.
Thank You, I will look for it as I can't upload my pics to flickr yet.
