My page shows only black! Help!

I have almost finished my first course, and it's due at the end of today (it's 3pm now, I've got 2 hours left). So I was just going through and fixing up little bits and pieces, when page 34 decided it would show nnot content, but plain black! What is happening?I don't really want to rebuild this page, as it is the biggest of the whole course. It's mainly text, but it's 955 x 2700px, with a background image jpg across it.What happened right before it went black was I imported a swf file, just a little one, like 2kb. When I went F9 to view in the browser, and then again when I tried F8 to publish to HTML, was that the back ground image was gone, all the text was gone, some specially formatted text remained, some links remained too....I will try removing the swf and see if that fixes it, actually, it looks like Lectora has "removed" it itself! If anyone knows what's going on I would be grateful to know!
