Nope it's only one. Everything goes fine and works well prior to installing. The sys tray icon is there and all lit up with the two green monitors flickering away happily, but as soon as I reboot the icon sys tray Icon goes cold with the big red X, which means it's not connected. But as I said I can browse the network no problem at all, the only annoying problem is that the icon shows me differently, makes me think that it's something to do with the registry settings.
