That would likely indicate VoiceAttack is being prevented from connecting to the internet on your machine.
If you search the Windows start menu for "Allow an app through Windows Firewall", open that, and check the "Allowed apps and features" list for "VoiceAttack", does it have a checkmark on the left-hand side? If so, does it have checkmarks for "Private" and/or "Public" on the right-hand side?
That is assuming you're not running non-Microsoft security software/firewall.
VoiceAttack will need internet access for initial activation, update checking, and any actions that utilize an internet connection.
