Thanks for the contact info. I'll try to contact them tomorrow.
And regarding your question - yes and no...
Basically what happened is this:
2 places: place A and place B
place A is where I want to set up the DNS-320L
I started the setup in place A, I remember it initially loaded ShareCenter, but then when I linked my myDLink account is where the problems began. Immediately after the "click" the ShareCenter under 192.168.1.x stopped responding and I was getting ERR_CONECTION_RESET. Probably around this time I've started this thread.
Then I took the DNS to place B tried to set it up and it worked just fine, but I realise now that I didnt link the myDLink account.
So the next day (this morning) I tried again the same thing at the place A but it didn't work at all. Then I took the router from place A to place B and I tried it, it worked! I then upgraded the ShareCenter's firmware and when I linked the myDLink account it stopped working again...
so thats the story ;-)
