The error message is misleading in early versions of ID. .indd files cannot be opened in versions of InDesign earlier than the one they were saved from.
You need to either upgrade the program, or ask whoever supplied the file to send you a .idml file, and a PDF so you can see waht is lost/changed when you open the .idml.
Thank you for your response. He actually did send it to me as an .idml file
and I just can't open it. The error message, which I've attached, says that
I need to update my plugins, but when I go to updates under help, it says
there are no updates. I'm just not sure how to resolve the issue. If I have
to update to CS5, then I will, but it'd be great to keep CS4. Thank you so
much for your help!
I've attached another screenshot of what message I get when I try to
update. Thank you again!
Sounds like he just renamed it from INDD to IDML. He has to export the file as IDML.
Or else you need to update CS4 to the 6.0.6 patch...

Thank you - I realized that after I sent it - sorry not familiar with
forums. I will investigate the 6.0.6 patch.
