I'm having the same problems with all new and exisiting documents
"modification not allowed because the document is locked"
I've clicked on Help/Activate product but nothing happens.
What can I do?

If all new and existing documents are locked for editing, then
it's probably because you have not activated your Word/Office
software, or because you have an expired trial version of Office
2003. What happens if you start Word and click on Help |
Activate Product? 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
purchase a key online.

"This modification is not allowed because the document is locked." That is
the very annoying message I continue to receive when trying to start a new
document. What is going on? and Why can't I unlock the document so that I
can begin my paper?
