Today, I was organized early because I had work to do. Unfortunately I'm like a dog with a bone, when I have technical issues, so I rang AppleCare and spend an hour and three quarters on the phone. Two technicians later, and we had it solved. Resetting the Time Capsule just gave it a conniption with my passwords........on both computers!!!!
All fixed now. I have deleted old backups. I'm not sure how the old ones are supposed to 'fall off' when room runs out, but I got an error message saying that my TC is full! I'll just delete them manually. I don't need to go back that far. Love the automatic backups though, because I wouldn't remember.
Ahhh...............I feel better now.
