Mana Games

Just got an error message on the screen: Bug #531 Data Invalid. Please reinstall the game."
Not sure I want to do that as I don't want to lose my progress. It was fine yesterday.
I'm running the game through Steam, with Sam's Megapatch.
Thanks.

I re-installed the game, and Sam's Megapatch, losing my career in the process. I'm not happy about it. I'm guessing the bug will re-appear when I get to the same tournament.
