2013 presentation's animation not working in 2007

[captainship]

Hey everyone, I need help. I'm having a presentation tomorrow and I've spent all of yesterday preparing it on my home computer (which has Office 2013 installed + windows 8.1).



However, today I went to practice the presentation on the laptop I use to go to work (which has office 2007 + windows 7) and the presentation opens, but the animations don't. I've tried removing them all manually and putting them back again in the 2007 office but it still doesn't work. It's as if it doesn't have any animations. And I really need them to make my presentation smoother and easier on the eyes.

I tried saving the presentation as .ppt, but the same thing happens. This presentation was a pain in the butt to make. I really don't want to have to start another one from scratch on 2007.

Can anyone let me know what I can do to fix this? Thanks.
