Lost uPnP?

N-Serve works, N-Stream via USB input works, US-SSD N-Serve shows everything is online and working, I can serve via SPDIF .....but..... I have lost the uPnP capability. Can't get it running and the NDS sees the Twonky server on the same drive as the music store but not the store itself, which is available to N-Serve and it all worked well yesterday.

Its just gawn? 

Also using IP for the US I can log-in via Safari/Mac but the pages keep refreshing every 20 seconds on their own? 

Trying PC

Any ideas chaps?

Thanks
