Clip+ Syncing issues

[diechipmunk]

I've had my Clip+ for at least a years now, and a Clip for a few years prior. I've never had a syncing issue. All of a sudden, I could not add music through any method. MediaMonkey would co through the sync process, but the only thing that would actually transfer was the album art, and that would end up in the root directory, not under music\artist\album.

I changed the USB connection protocol to MSC, but I can't see any files at all on the clip through explorer. (I'm using Windows 7). I decided to try a MM sync anyway, and it worked like a charm. I can still only see the new album in explorer, but I can still play any of the previously loaded music on the Clip+.

Any idea what could have happened? I'm planning to do a reformat and start from scratch. Any other idea or thoughts? I have RockBoxed my older Clip, but I find it more of a pain to use that the Sansa OS, so I wasn't planning on changing the Plus.
