That is what I presumed since logging on to Ironclad Online mysteriously started to give the "Disconnected from Ironclad" message the day they said they were converting the servers over to the new patch, v.1.1.
My problem, however, is trying to find the patch. Impulse doesn't work, it never has on my computer. Uninstalling it to get to the Stardock patch download page simply directs you to get Impulse. I am in a Catch-22 here.
Now not only can i not update, but I can no longer play on Ironclad either.
