Can't edit a specific document in Word 2007

Question

I have a document in Word 2007 that seems to be read only. There are forms in the document that I can type in, but I can't edit or reformat the rest of the document. There is probably a setting somewhere I can flip to make it editable again but I can't find it for the life of me.

FOLLOW UP:

The "Protect Document" button only had "Unrestricted Access" checked, this was one of the first things I checked. However, when I tried checking "Restrict Formatting and Editing" it brought up the Restrict Formatting and Editing sidebar, which stated:

This document is protected from unintentional editing. You may only fill in forms in this region.

With a stop protection button on the bottom, which of course solved the problem. I think that menu item just has a bad name, it should be "Restrict Formatting and Editing Options or Settings"

Answer 1

Is the file "protected"? If so, go into the protect/unprotect section and unprotect the file. Then you should be able to edit any part.

If you have the developer tab enabled, there is a quick section in there to change the restrictions or protections.

To enable developer tab: Go to the big main Word menu (the big bubble in upper left), click the "Word Options" at the bottom, the default page will be the "popular" options, check the "Show Developer tab in the Ribbon".

Answer 2

copied from Unprotect a Word Document so please vote him up over there.

One possible solution. I think there are others as well.

1.) Open a protected document in MS Word
2.) Save as "Web Page (*.htm; *.html)", close Word
3.) Open html-document in any Text-Editor
4.) Search <w:UnprotectPassword> tag, the line reads something like that: <w:UnprotectPassword>ABCDEF01</w:UnprotectPassword> (password is already in hex-format)
5.) Keep the "password" in mind
6.) Open original document (.doc) with any hex-editor
7.) Search for hex-values of the password, which is stored in reverse order. (e.g. If password is 0xAB 0xCD 0xEF 0x01. Then the password is in the .doc file as 0x01 0xEF 0xCD 0xAB)
8.) Overwrite all 4 double-bytes with 0x00, Save, Close
9.) Open document with MS Word, Select "Tools / Unprotect Document" (password is blank)
