Just wanted to let you know about a small issue with Windows Updates. I am running Desktop TI2 in a dedicated USB PCI card, running Windows 10. No problems at all, but Windows then decided to install KB3140743 and hey presto, no more Virus connection. Nothing in my DAW (Cubase 7.5) and Virus Control couldn't find the OS version so thought it needed an update.
Uninstalling the update through Control Panel has solved the problem. Just wanted to post so it'll help if anyone else has the problem...
