Yes, I have the same problem. It was working before, but I just upgraded and installed two new 2TB hard drives and now it stopped working. I enabled UPNP and configured it to look into a specific folder I created for all my media files and had it scan. It then locked up. I couldn't access the Dlink menu anymore. Whenever I tried to put in the IP address of the Dlink it says that the webpage doesn't exist. I can still access all of my files from Windows though. I tried shutting it off and back on and then I could log in for a few seconds and then it locked up and the same issue. The only differences between now and before when it was working is before I had different hard drives. I think before I had two 1TB Western Digital or Hitatchi and now I think I have Seagate. Another thing different is before I had it scan my whole hard drive and now I'm telling it to scan a specific folder on the hard drive. If you figure anything out then please let me know and I'll do the same.
