If you sit still do they populate? Can you scroll up and see some logos, but not all? If so do they ones that weren't there reappear after a few seconds or no? Trying to see if the cache is stopping entirely or just taking longer than it should. Also could you look in \\LaunchBox\Logs\ and grab a log when you are seeing that behavior and PM it to me so I can take a look, see if there anything in there that could give us a clue as to what is going on.
