Minimwach is "grayed" out

[birdmanmike]

Simon, hi. been lurker on forum before but never needed help, so . . .

This Minimwatch greyed out - I am getting that now but never had before last updates.

Concern is it all usd to work OK, Minimserver on Synology NAS and Minimwatch on Windows PC and also a Macbook Air. Regularly updated the Minimserver but rather let the watch go as just used the server stop /start when re-indexing.

Latest Minimserver update is fine. However, the Minimwatch, also updated, just shows gray - on either the PC or the Mac. I have not changed anything network-wise, the firewall is not blocking and have tried switching it off also anyway. The PC is wired by ethernet into a switch - same switch as the NAS. The switch is also a wireless access point - which is used by the Mac. All are on the same subnet. The ohnet.subnet field in properties (watch) is blank however. I have tried inputting the correct subnet 192.168.1.0 but MinimWatch justcomes back with "Unknown component name".
Alos strange- when I try refresh - I get An unexpected exception has occurred java. lang. NullPointerException. OK to relaunch etc. Then the log window won't close and Minim watch hangs and has to be force closed.

Not firewall, don't understand why subnet cannot be entered, but happens on both the Win version and the OSX. Me, I'm at wits end. Possibly Java?.

Neither machine has any problem accessing the NAS music and both and ipad/iphone can access Minimserver via UpnUp over my Cyrus. it's just Minimwatch.

Any help gratefully appreciated, thanks, Mike
