“Unable to delete automatically generated client recovery file."  Sounds like they’re referring to the automatic recovery system in use when your working on a file… it failed or got corrupted.

Tried updating? If all else fails uninstall/reboot/reinstall … copy your client files to another directory first… it’s the weekend… not likely you’ll get a reply from developers til Monday. If you have a solid backup of your files you won’t lose any data… over the years, I’ve resorted to this a few times 

one other thought… after rebooting, during the reinstallation process, check task manager to be sure that no PS services are running that may be hiding in startup.
