Hi, Mr. Ed. Actually, I do not do log off, nor log on, I just boot up.
However, I have used Safe Mode as Administrator and myself, each individually, and have tried to access Updates from each one. Neither has worked.
I do have tremendous problems with my 'wifi' connection. It constantly disconnects and I have to 'repair' more or less to get back online. I do know the most recent, a few minutes ago in Safe Mode as myself, the connection was working but wouldn't do the Update.
