LMS running on Picoreplayer not scanning music folder

Ive set up picoreplayer on a RP to point at my old faithful NAS Duo - not having any Linux skills I was a bit apprehensive but all has installed ok and Im really impressed how easy it all was - the problem I now have is that when I point at my music folder the scan kicks off with zero results - I suspect strongly that its a combination of the field settings within LMS and the NAS Duo permissions on the shares, but Ive tried all sorts of combinations. Be grateful if someone could help - what information could I post? this for example is the way I am pointing at the NAS from within LMS but IM not even sure if that is correct. Thx (I did wonder if I made a mistake in the install in the partition of the SD)
