Thanks for your reply. I have a Mac, updated software. I uninstalled and reinstalled TT21 many many times over the hours I spent with tech support, rebooting, clearing web history, they even sent me a new access code to use for the download. None of it worked. Please advise where to find the library file that needs to be deleted that you mention. I'd really like to be able to access TT21 under my regular user account as I have always done.
