n-Stream Problems with ALAC files

Hello,

I use Superuniti to stream music from NAS and another network drive and drive it from iPad through n-Stream. 

It does have some bugs f.ex. displaying wrong cover but generally works fine to me. But there is a problem with playing ALAC files from network disc in playlist mode. While n-stream is displaying content etc when I'm trying to play a song or album it show the message "0 track were added" and obviously nothing happens. It does play however these files when n-Stream is in uPnP mode. Anyone has come across such a problem? Is there any way to force it running? In other words I can't create any playlist with ALAC files. 

I have n-Stream 3.12, Superuniti soft v.3.17

Thanks for helping.
