This has been happening to me for the Last three turns as well. Unfortunately, it isn't the first time, and I doubt it is the Last. This is just something that happens to some players on Mose's server.
What I do is bring the Task Managet up, and kill the Dominion II application as soon as I see I am not getting through. Then I try again. And again. Usually the third or fourth time does it. Whatever you do, do not assume that the server is down. Keep trying or you will stall.
By the way, I think that, at least once, I had to try more than fifteen times...
