How do I update my plug-ins or my current version of InDesign CS4? I need to do this to open a document for my school newspaper. My computer won't open the document until I update the plug-ins or my version of InDesign. Will this cost money?
That document was likely created by a version of InDesign later than yours. CS4 is now 5 versions out of date.
Ask whoever sent it to you save it via IDML. Don’t count on a perfect conversion. Get a PDF as well.
