King's Bounty SaleI can't recommend King's Bounty with 64-bit Vista as the OS anymore (unfortunately), but for everyone else, it's a fantastic game. Ty Sleck let me know that it's on sale this weekend for $22.90 at GoGamer. That's an insane price for a wonderful game.
As for my own problem, two people (one with 64-bit Vista, one with 32-bit) are testing my last save. If it runs on both (or one), then it should help me narrow down what's going on. If it crashes on both, then unpleasant thoughts and curse words.
