So Steam updated Sins the other day, I opened the game today, and found I'm no longer able to play any of my save games, with the error "save game is from an older version of sins and cannot be loaded".

A quick google search shows that this was an issue when the game went from beta to full release, but can't find anything more recent.

I'm pretty disappointed in this, as I was over 12 hours in to a large campaign and about 2 thirds through conquering the universe, uploading episodically to YouTube.

Is there any way to sort this out? I don't want my campaign to be over!
