So it seems (now that I've finally got my MP3 drive recognised and the indexing done) that I have a new error... that I have 'too much stuff' (I'm paraphrasing the error that comes up in the Set Up Music Library screen). From another forum I found this wonderful nugget:
You can see the Network Matrix by using a web browser to go to http://###.###.###.###:1400/support/review (replace the #'s with the IP from one of your ZonePlayers. You can fnd the IP on your handheld Controller's Settings-->About My Sonos System screen, or Help-->About... on the Desktop software).
And within that I found this:
Store Size 3604480
Store Used 3604390
Entries Size 262144
Entries Used 75493
Okay, so I haven't broken the 65k limit for the number of tracks I can store (I'd have been amazed to be honest), but I do seem to have hit the headroom for 'Store Size' and I've got 21,988 conflicts, which doesn't sound good either.
What do those two stats mean in practical terms, and what can I do about it? Anyone know?
