Still I don't want to risk it if I can just install Acrobat 11. I originally thought there was something wrong or incompatible with 11, that's why I wanted to try another version. But now I don't think that's the case; it's probably the way I've formatted my Word documents or some settings in Acrobat I need to change. I experimented a little yesterday with shorter page lengths in Word and Acrobat didn't seem to have any trouble saving all the graphics. Granted it's not a whole document but it's a good sign. If worse comes to worse I can always just insert the missing graphics into a PDF with Acrobat. I was hoping it wouldn't come to that, but...
