Hello 
This morning on two different PCs, one running the 2013 Suite, and the other the 2013 AV+, Bitdefender has yet to finish downloading an update. Both the Watchdog, and the update panel are going in circles, but the update is not completing 
I did try the alternate download address in the update location (http://upgrade.bitdefender.com/) to no avail.
Anyone else experiencing this? I did check my network settings, and all seems OK there.
Thanks
