Editor Error - Please Help!

[[H3D]Pendragon]

I finished a map with one huge bug, I forgot the sky box. I did a full build and saved it, then I cooked the map. I can now play it in instant action. However every time I try to open the un cooked map in the editor to make that one change, it crashes.

The file is located here: http://files.filefront.com/VCTF+H3D+ChristmasMorningut3/;12532427;/fileinfo.html

Log file shows this error:

If any of you can get this file working, I beg, please help I spent to much time on this map to start over. Even my last backup was over 8 hours of work ago.

Ok, here is the Published (cooked) version. I still cannot get this thing back into a working un-published version.

I tried exporting everything one by one out of the map, then saving it (minus sound cause I think it was the sound that broke it).
Then I imported everything into a new map. None of the static meshes or materials that I had made, which made up 90% of the map, were imported.

If that would have worked, then I would have been set.

Here is the cooked/published one:
