I found this helpful article about how to open a CS5 document in CS3.
http://help.adobe.com/en_US/indesign/cs/using/WSa285fff53dea4f86173837 51001ea8cb3f-6d4da.html
Unfortunately this does me no good because I need to have CS4 in order to pull it off. I only own CS3 and CS5. Is there another way to get a CS5 InDesign document into CS3?
Please help!
