I am getting the same error. I have not moved to any other screen or pressed any other button. I clicked the scan/scan again button and than 'update all'. I also tried to update a single driver and got the same error. I used the 'check for updates' function and I am using the latest version.
Since this is a new function, perhaps my firewall does not allow this 'suspicious' activity through which software is updated? I'm using Bitdefender and the notifications list does not show any related warnings or other messages.
