Prezi really slow to react whilst editing

I'm creating my first Prezi and I have imported around 35 swf images. These images were exported from Adobe Illustrator. I have since seen that apparently swf exported this way will cause a problem when using the path tool but my main problem is that my Prezi is very slow to react when I try editing it, it is almost impossible to do anything. The Prezi is currently 32.2mb and I haven't done anything other than add the swf images to it. It's so slow that I can't add any animation. If I try to move around the screen or zoom in it takes about 30 seconds to respond to what I did with the mouse. How do I solve this problem?
