Sorry to hear about your experience. Would you mind sharing the version of the OS & InDesign? Do you get error while exporting this specific file or all? Are you saving the file on a network location? If yes, try saving it on a local drive first.
You may also try saving the file as IDML or export the file by dividing the pages to see if any page/graphic/link is the cause of failure.
Let us know how it goes. Looking forward to your response.
