Try changing the format of images on that slide. I usually remove the images on the slide, one at a time, until the slide plays back correctly. Save the image as a JPG or GIF image and re-insert it, then the presentation should play back.
it works just after i combined the three seperate cliparts into one and reinsert it into the the slide which stuck.
Change your images to RGB.
No Greyscale or CMYK.
