GrudgeBringer, your first post was a little hard to understand. I'll do my best.
You don't need the pretender or anything like that. You don't need the turn file from last time the game started - that game is dead. You do need the .trn file that was sent out last night (GMT, about 9 hours ago anyway). That needs to be put in your dominions3\savedgames\FreshMeat folder, and you should then be able to play the game.
If you've somehow deleted that file, you can request a resend. To do that go to
www.llamaserver.net, click on "FreshMeat" and then click on "Request turn resend" at the bottom.
Hope that helps.
