The import button is grayed out as are the menu items for importing, therefore I can't access the import dialog screen. I've opened older backup catalogs that were saved prior to this problem and still get the same result. However if I create a new catalog the import function works as normal. I've done Google searches for the problem and have found nothing. I have a 13,000 image catalog that I've used for years and this just suddenly happened. I'm using the current updated version of LR5. I assume its something very simple and I'm just missing it! Any suggestions will be appreciated.
