CMS Page Break isn't working
 

I have a huge article that is set to publish on the 16th of this month. it has somewhere in the neighborhood of 170 images and the article itself is HUUUGE...

I have tried putting page breaks in the article so that it will break up the article into multiple pages but, it isn't working.

When I insert the page break (by clicking the page break button), it puts one in the article. When I save and preview the article it isn't there. Then when I go back to edit the article the page break that was supposed to be there is gone...

Any ideas?
