Got Mom fixed up. Mostly had to do with getting wayyyyyy too impatient and contually punching random buttons when the computer wasn't responding. Couple that with finally closing the top in frustration and interrupting an update. It took a couple of reboots to get the update straightened out but seems to be fine now.
... until the next time...
I'm going to take the suggestion of installing a remote login setup. At least then I can have some amount of direct input when things get wonky.
