A while back, my OS crashed. It had to be restored to a previous date, and it chose the date that I updated my version of LR to the newest. Ever since then, when I restart LR, I get the message: Unexpected error opening catalog. My ONE catalog I had will not open to save its life. So then I click "Choose a Different Catalog," and click to create a new catalog. But that's another problem--I can't! Each time I try to, I create a new folder for it (as it tells me to), and then name a file to save it to. I click "Save," and nothing happens. LR doesn't create a new catalog, nor recognize that ANYthing was just saved.
NEED HELP!
