My slideshow has 82 slides, but it gets stuck at slide 23...

I uploaded a powerpoint presentation that had 82 slides. It works great up until I get to Slide 22. Once I click to slide 23, it freezes up everything. However, when I just type in 24 from a refresh of the page (so as to skip #23) it goes right on through to the end. Slide 23 doesn't have any special or different elements to it than the other 81 pages.

Could someone tell me what I'm doing wrong?
