I see. Very well.

I'd recommend running the autopatcher as soon as this is resolved, or you give up on trying.

What I'm going to ask you to try now is a longshot, but who knows.

Your saves should be labelled like this in your directory:
000000001-Quick-Save
000000002-Auto-Save
000000003-AvatarOfLight
etc

Your quicksave's number may have been taken by a new autosave for instance. Make a backup and manually remove whatever save shares the number.

If this doesn't work either feel free to send me your quicksave through MSN or E-mail. I'll try to resave it as a normal save. I have NWN and SOU installed, not HOTU. But you will have to patch your game to make this work.
