Ok here's the deal I bought my copy of Sins through stardock digital download (which I guess means I have the collectors edition). My roommate bought it in a store. We can both play single player fine and can both play ICO separately but whenever we try and connect through local Lan games we get a 'data differs from host' error. We've tried everything I can think of to fix the problem but have not been able to get it to work.
We've tried:
1. Reinstalling both games
2. Updating both games to 1.1 version (though we have had the problem since the first release of the game and have tried again every patch)
3. Tried using the useless search function on these forums to find out if it's a known issue but no matter what I search for there are never any results
We both love the game but if we can't get some kind of solution I think we're pretty much just gonna give up on this game because the AI just doesn't even compare to playing against another player, which is why we bought the game in the first place.
Also one more note we had a third person who bought the game, installed and updated it and we were all getting the same error no matter who tried hosting. Kinda hard to have a lan game when you can't get the game to connect.
