I have just started to use Norton Zone and encountered the alart, could not bind with server, plase try again later.
I installed Norton Zone three Macs and two are ok but only one shows the message just after starting Norton Zone application.
I tried to install it again but in vain. There is no folder named Norton Zone in my home directry conparing to the Macs work well.
Could you please help me to use Norton Zone on my macbook air running on MacOSX 10.8.5?
