Remote on Windows 8.1 | Error code -3

Apologies for lack of updates but the reason is that simply, there aren't any! Both Level 2 and Level 3 support have now had remote access and seem unable to resolve the issue. As this is on my main work pc, I am now calling a halt to this nonsense at my inconvenience, as I can't afford either the time or resource, let alone risk on which my work relies. This needs to be fixed rather than attempts at "patching" individual installations. Having been a regular Netgear customer for many years, I will seriously be considering my options when the time comes for future upgrades or installations.
