When I run LR CC, it tells me the catalog must be updated for use with CC. Then a progress bar starts, but almost immediately I get an error message telling me that Lightroom must close, then "Windows is checking for a solution to the problem." Of course, it never finds a solution, so I cannot use the updates to a program I am PAYING for by subscription. What do I do next? I am running Windows 8 (64-bit) on one computer and Windows 7 (64-bit) on another.
