It seems that more often than not when I quit the game, everything seems fine, and I don’t get the "Alabama" error message (although I have gotten that a couple of times), but when I try to play again, minutes or even hours later, the game won't launch and I see that error message.
Luckily, there's an easy work-around for this: you find the game in task manager and find the avowed folder which will show 2 files stil running (forever apparently) and you can end the task there and then it will launch fine.
Also, is there a "known issues" list yet somewhere in this forum that I haven't found?
