Cannot Save or Save As File After Redacting Document

[tossc3]

I have a big 3500 page document that I am trying to redact content from however everytime I try to apply the changes I do not get the save prompt so the changes never save. What should I try to resolve this?

What's the exact version number of the application (You can find it out by going to Help - About Adobe Acrobat)? What's your OS version?
