Storyline won't publish when I add the logo

Hello,

I was able to publish my file until I added a logo to it. I have tested it, and when I completely delete the logo (not just disable it--i have to completely delete it), I can publish just fine. If I have the logo in the player, even if it's disabled, I can't publish.

I have opened, resized, resaved the logo and no dice. All of my files are local. Ideas? Of course, it's Friday night. Of course, my project is now late. I'd really like to save my butt over the weekend and have this ready on Monday morning. 

Thanks
