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

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.
