How can I open this Indd file in my CS4 version? It is stating that I am misisng plug ins then it won't open the file. I'm guessing its probably a CS5 version file... Not sure. How do you tell? Anyway, I can I open this thing?
Worst case - How do I upgrade to CS5? Is possible? I can't find anything to upgrade to from CS4. They make it so hard to find.
Thanks for any insight or help!!
