Just a heads up but I was just prompted to update to the latest version but after installing it, got a message to say it could not find my library, do I want to load with a blank library? I tried the 'no' option obviously a few times, hoping it would fix itself, but nothing worked so I took the risk of trying the 'Yes - load with blank library' option.
After a few seconds staring at a blank NA and doing some deep breathing it did finally refresh itself and now everything is showing so just don't panic if this happens to you too - just allow it some time and if you have to select the blank option it should not stay blank for too long
