Project files saved in a version earlier than Microsoft Project 2000 can't be opened.

If your file is from an earlier version, open it in that version, click Save as (File menu), and save in MPX format. Open the MPX file in the current version of Project. When you use this method, project data is imported, but formatting is lost.
