Animations on ppt slides are not working

I created an elearning course using ppt 2007 and and Articulate Studio.  After putting in all my engage interactions, I went back to the ppt slides in the beginning and end that start and finish the course and put in custom animations.  When I preview the presentation through Articulate none of my animations come through.  Same thing happens when I publish.  I'm not doing any type of voice narration, so I can't synch the animations up to anything.  Any suggestions? 

Please help!
