Try it again.  The ICO server was down earlier for a couple hours.

Got the same problem. I read somewhere that it's the gamemaker's fault and that we can nothing do against it but wait.  

-.-  grrrrrrr

i've had the problem since I got the game. Read the TechFAQ, disabled firewall, updated game, and still can't play.

I find it such a nice feature that they include multiplayer, but can't figure out how to implement a logon screen. I didn't pay $40 for this.

Waiting, waiting... It can't be that it's always down when I try to get online! I've tried it now for several days!

And I actually bought the game to play it online because AI is never a challenge for me and gets boring very fast...

PS: I got a german version of the game and I read you can download the game also in English. Does anybody know where? (Impulse) Do I have to uinstall the game before I can do that? Thx for answer

Edit: Found now the solution. You need to update Sins to version 1.12 via Impulse and then it works. But it's stupid of the game makers not to write something like "Make sure you got latest version" to the error message. And actually I thought 1.12 was not yet available for a german version...

Hope it helps someone.

They actually use the Blizzard Downloader...

i had this problem but just downloaded patch 1.12 from impulse then it worked.

I'm having the same problem. I'll try patch 1.12 and write later to tell y'all if it works

i figured it out

I have version 1.12 and still no luck getting on, running vista 64 if that matters.
