Header Error

[XdragonSB]

I posted this in ZC, but I got no help at all in fixing it. (As in, I tried their suggestions, but it isn't helping)
When I open my quest it goes like this:

Loading Header... error.

And then it won't open.
I NEVER TOUCHED THE HEADER

I never even touch the header unless I'm making a demo or I am finishing the game. (I made 5 games so far.)

Anyway, I don't want my latest quest to go to waste.

This is the main topic.

PLEASE HELP.
(Yes, I used TWO file restoring programs, they don't help.)
(Yes, I downloaded the LATEST BUILD)

Will any other quests work? Try using another quest.

[XdragonSB]

Yes other quests work.
It's only my quest that doesn't work (the one in the link in the link)

PM a developer with details of the problem, a link to the quest (and password if used), and the contents of allegro.log.
