PDFs will not open in Windows

I've made a spiffy document in Pages but when I save it as a PDF (from Export or the Print dialogue) it won't load properly in Acrobat Reader 8 on Windows XP. (It loads fine in Preview). Acrobat gives the following error:

Could not find the XObject named 'FM9'. An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.

Does anyone know why this is? You can see the PDF here.

 

I made sure that it had .pdf on the end - didn't help I'm afraid, but good thought.

I notice that when it loads up the PDF it puts all the elements in one by one (it's not 'flat').

 

Fixed!

Sorted! I've worked out what the problem was!

The very bottom couple of pixels of the very bottom line of text were slightly cut off by a text box that was just too small. This screwed up Acrobat when it tried to display the text.

Obviously Acrobat is a bit less robust than Preview.

(I also notice that the fonts are wrong in the Firefox PDF viewer... and that it generally just looks a bit more crappy in Acrobat than Preview... but hey, I guess that's life...)

 

I lied. Now that it's fixed, the fonts work properly in the Firefox viewer. Must have been part of the same problem.

Still looks a million times better in Preview than anywhere else, though.
