That may be the case, I was running MMW on a Windows 10 system. I installed instead on a system running Server 2012 and it worked like a charm. Thanks for your help.

couldn't play via UPnP. LogID is Z2K2MH9RCX

Can you play files from the same Playlist if you approach it through UPnP in MMA? If so, in case you're doing a wifi sync send a debug log from MMA right after you experience this and post the logID here.

I'm trying to sync from MMW 4.1.24.1883 to MMA 1.3.4.0854.

I have MMW gold and MMA pro.

It used to work fine, now when I try to sync a new playlist I get "failed to download", in this case it lists 400+ songs that didn't download.
