Yeah. I have left the machine running. I ran the install around 6pm EST yesterday. Had it running actively the whole time, even trying to force the sync with multiple reboots. Decided to leave the computer on overnight to see if it would sync then, but no dice.
Currently this is the issue with two of my machines so far that I am trying to get the MAV to run on. I know it syncs every 6 hours or so by default but it has been 12 hours now.
