Problem with activation

I am using Pianoteq with a dedicated audio laptop on Windows 8 x64. Due to latency issues network and lan adapters are deactivated in device manager. Sometimes (I think one time per day) there comes the message that Pianoteq isn't activated, although this isn't true. So I have to activate network in device manager to get a wlan connection. Then Pianoteq activates itself by clicking on "Quick Activation". This is very cumbersome. And of course if there is no wlan connection available I can't even use Pianoteq! Any ideas what is going wrong?
