And as for your first question, yes, that isn't normal. The game creates a "dominions3" folder in your home directory and stores the key in a file named "key". If the folder exists but the key file doesn't, check that you have permissions to write to the folder. If the folder doesn't even exist, you would also have trouble saving games, so I'm guessing it does exists.

If the key file is present, maybe it's gotten corrupted. Try deleting it and see if the game re-creates it.

That's all I can think of. Post again if that doesn't work or you need more details.
