How do I unlock a section?

[Lindsey]

I must have hit a button to lock a document that I am working on and I can't
make any changes. The taskbar keeps saying modifaction not allowed because
selection is locked. How can I fix this?

Does this happen in all new and existing documents? If yes, then maybe
you have a trial version of Office 2003 or 2007, and the trial period
has ended. Or maybe you have not activated your Office software.

What happens if you start Word 2003 and click on Help | Activate
Product, or if you start Word 2007 and click on Office Button | Word
Options | Resources | Activate? If you are already activated, a dialog
box saying so will appear. If you are not activated, the Activation
Wizard will start. If you have an expired trial version, a dialog box
will prompt you to enter a valid product key or convert (purchase a key)
online.

This happens in Word 2007 when you open a document in read-only mode
because it is already open in another application.
Hope this helps.
