I am getting this error when I try to open an InDesign file I created in an earlier version. "Adobe InDesign may not support the file format, a plug-n that supports the file format may be missing, or the file may be open in another application." I cannot seem to find any help info on how to fix this.

Does this happen with just a particular file or all the files produced with the older version? If it is just a single file then it might be the case of file corruption. If it is indeed a corrupted file, you can email a copy of the document at email@example.com for the Adobe engineers to try and salvage the file for you. If the file is more than 10MB in size, upload it to a cloud service like dropbox and email the public access URL. There is no specified timeframe within which you can expect a revert from Adobe guys, so if time is of the essence and you won't mind a paid solution, try the following
Edit:- The latest version of InDesign also comes with a corrupt document fixing service, it should prompt you for sending the file to the server when you try to open up a corrupt file.
InDesign can't open Ai, PSD, or jpg files, so the error is perfectly normal. You can place these files onto your InDesign document but not open them directly. So instead of using File>Open use File>Place menu to place these files on the open InDesign document.
