FULL MISSION EDITOR glitched up after I had my computer crashed. HELP ME!

[Gabaryt]

I was playing IL2 in editor.
Then my computer crashed, because there was no electricity.

When I launched IL2 next day, I found out that editor is glitched up - the only option under FILE menu is Exit, and its not even working. You know, I load up the editor, blank blue page s normal. I click File, because I want to choose load, but there is only EXIT option, and it doesnt even work.

HELP!
