Well, I reinstalled A3 recently, and got a new key for it, and the game itself won't let me register. It accepts the new key, thanking me for supporting shareware and blahblahblah, but when I press "ok" on that dialogue box the game freezes. I can only assume it is freezing upon trying to save my registered status to avernum3.dat because when I restart the game, it's still unregistered. Help!
edit: Oh, what on earth. I open the game one last time to just play through the demo while I sort this out, and it's registered now! Whee.
edit edit: However, it still annoyingly crashes almost every time a dialogue box comes up, including in Settings so I can't even turn off Help so that I could maybe play. Wah.
