When trying to open and use the CommonLook PDF Validator, if you get an error message that says the document is corrupted and the PDF Validator can't open, there are a couple of things you could try in order to fix this.
- In Acrobat, try deleting the tags in the Tags tree and then adding tags again. Sometimes this will fix things.
- Go back to the source file and try to re-create the PDF again. Perhaps, if your authoring tool has multiple ways to export a tagged PDF, and you used one way the first time, try a different method.
- If you have CommonLook PDF (the remediation software) try running that. CommonLook PDF has a tool built into it that automatically fixes a lot of corruption issues, behind the scenes, as it's opening.
- Send the PDF to CommonLook. We can take a look at it and possibly "debug" it for you so that you can test it. Use the support@commonlook.com email address, include the PDF, and a description of the issue (you're getting a corruption error when trying to use the PDF Validator).
