I've recently updated to Ver 3 due to issues with Ver 2 that I was running (see other thread).
All has been well for some weeks, now it won't update and simply says "Download Interrupted".
As to who or what is interrupting it I have no idea.
I did try rebooting my machine yesterday, but when it rebooted I had my back to the screen so didn't see exactly what went on - however when I turned around again, it appeared as though NOD had updated.
I don't feel like rebooting every day!
