Sadly not a song title, but the message did seem to be a bit fresh !
The machine had crashed. Sorry I don't remember the exact chain of events that led up to it, but the machine was frozen at the time. Most of my problems seem to come when discs fail to complete ripping.
After waiting for some time my only option was to turn it off and on again. After that, it was sluggish doing anything - wouldn't load CDs, scan disk, save. I tried doing Web Upgrade but the download failed. I turned off and unplugged for a while. Turned on again and it seemed to be okay but I decided just to leave it on overnight.
This morning successfully did the Web Upgrade and now it seems to be back to working as normal.
