Hmmm ... what do you mean by "upload a CD"?
The NServ app does store information on albums from its last use and can appear to be "live" with the usual views appearing but it may not actually be connected to your UnitiServe
... the lack of a "playing" button would seem to suggest that this is the case; although note that this button does not appear on every page.
In my case, when this happens, the "playing" button is replaced by a "connect" button;
if this is not there then go to the "mor" tab and then "settings" where there is an option to connect to your server.
hope this helps,
Allan
