Keynote to PowerPoint

[boovish]

I have no idea where this goes so I'm just putting it here. I just exported my school project to PowerPoint, and it gave me an error saying something was wrong with the formatting, and then it just crashed, without allowing me to save it in the normal file format. I tried to open the powerpoint version, but it just crashes giving an error about trying to open it with the keynote converter. Please help! Its due tomorrow
