I'm trying to access my device list for my 10 item license for Norton Security with Backup. I have used all 10 slots, and have a second 10 item license. When I first log in to my account, I can see the first 10 devices. When I click on one of the devices, to change the display name, I receive the above listed error. Once this happens, I can not see anything under the devices list until I log out and log back in. I can see the devices when I look under the 'services' tab, but that is all. This has been occurring the last 2 days, when I first installed the product.
