NW-A45 Walkman - missing new tracks and playlists

[marukomu]

I've been using my A45 for a few years now and it has been totally fine in terms of transferring things from my laptop to the Walkman. However, I have recently encountered a couple of issues:

1. I sync the Walkman (from Musicbee, which is what I've always used) with the SD card in the laptop (again, this is the method I have always used) but when I put the SD card back in the Walkman it doesn't have any of the new tracks. I then need to rebuild the database from the reset menu, at which point the new tracks then appear. It's a pain as rebuilding the database takes ages (lots of tracks to rebuild).

2. Again when syncing the playlists are not transferring, even after rebuilding the database. I have tried limiting the number of playlists e.g. unticking them all and then just transferring 1 or 2 of them but still the same issue. 

I haven't changed anything else in the way I am using the Walkman or doing the syncing so it's all a bit strange. Anyone got any tips for this sort of thing?

Thanks!

OK, let me try with another card.

I downloaded music centre but the importing of my library was such a mess that it would take forever to get it back to the way I've built up over the years with musicbee.
