Not sure what it's supposed to look like, but nothing looks broken to me, but I also don't see a BG image in the code, so I'm assuming you took it out. For a BG image, find:
BODY { background-color: #CC99FF background-image:url(); background-attachment: fixed; }
And change it to:
BODY { background-color: #CC99FF background-image:url(BACKGROUND IMAGE URL); background-attachment: fixed; }
If that's what you did when it screwed up, do it again, leave it in, and let me know and I'll take another look, kk? :)
