Hi
I just came back to update this.
I posted here before I looked for solutions because I was leaving right after he called me and wanted to see if anyone had an answer by tomorrow morning.
It appears that this is a common problem right now, and that Microsoft is working on a fix.
In the mean time their, MS, instructions are to log in Safe Mode, then log out and back in it normal mode.
They say that this will fix it temporarily.
