I've made myself a presentation in Keynote '08, and I'm having some trouble exporting it to .ppt. I need to export it to PowerPoint as it's for school and our school only has PCs with PowerPoint on them. The export goes fine, but at the end an error pops up saying that some items went wrong in the exporting. Namely, my animations and transitions didn't make the switch to .ppt. Is there anyway for me to get them through? I'd really like to have those preserved. If there isn't, do you suggest any other alternatives so that my Keynote presentation is able to be viewed on my school PCs? I know of the open source alternatives (NeoOffice, etc) and MS Office for Macs, but I really like the effects and such that are available in Keynote.
