vtuner preset suddenly stopped working

Over the last 3  days 2 of my Danish stations on my ns01 suddently stopped working with  IRadio. The other stations worked fine. Today I edited the address for the stream on the naim radio guide page. I changed the address I have used for over a year for the  stream, with the one used when i browse to the station by finding the station searching on the vtuner site. The address was different from the old one, and the stream works fine again.

Another strange thing is that wehn I use the mac address to login this works fine until I want to change a preset then it seems I have to use my email and password even though I am logged on with the mac address.
