I've tried all the fixes I've seen online including deleting the .lrdata file, reset permissions in the SLCache and SLStore. Still only get the spinning beach ball when trying to launch. I'm on OS 10.8.5. Lightroomm used to work just fine. Any help greatly appreciated. Even tried downloading from the Lightroom site but it then launches cloud app and downloads through there. I've deleted it and reinstalled 4 times now with no luck.
