Hi, There are multiple factors both internal and external to InDesign application that can lead to document corruption. However, I can take a look and see if the file can be repaired. Please email your InDesign file to corrupt_indesign_docs@adobe.com and I will take a look at the document. If the file is larger than 10 Mb, you can zip (and password protect) the file and upload to Creative Cloud account (or Dropbox) and send us the document link. Regards, Sanyam Talwar
