Someone sent me a Word doc that consists of a form full of checkboxes and freeform fields. I am trying to insert an image version of my signature and a few extra freeform text fields so I don't have to print it and fax it, but the document appears locked. I went to Developer > Protect Document and made sure Unrestricted Access is checked, but I still can't modify the form. I am using Word 2007 and this is saved as .doc, probably 97-2003. How can I unlock this thing? Edit: Also, all but a few of the ribbon menu items are disabled. I can't change page layout, text formatting, or anything that pertains to modifying the document.
As you said it sounds like the file is locked. To open it you need to went to Developer > Protect Document, like you do, but then to enter to "Restrict Formatting and Editing". Now click Stop Protection at the bottom of the task pane and enter the password (if you know it, if the "Stop Protection" doesn't appear the file is not locked).
If the file is locked and you don't know the password you can try to use this guide to unlock it (disclaimer: I don't try this guide and I don't know if it works or not (but according to the comments in forum where I found it (with a brief search on Google) he is doing the job)).
If the "Stop Protection" doesn't appear and you still can't edit, comment here and I'll try to help more.
