I'm getting an error every time I try to run lightroom 6 on my windows 7 machine:
Unexpected error opening catalog - The catalog could not be opened due to an unexpected error.
it gives me the option to retry or choose a different catalog.
Neither option works.
I tried to see if there was an update in the creative cloud application, but when that application opens it just has a spinning wheel over a blank background.
