Persistent "document was created with an earlier version of Pages" error

Question

Since I upgraded to Pages '08 (3.0.2), Pages always thinks that I have created my documents with an older version — even new documents created with Pages '08. As a result, I am frequently shown this message when trying to save a document:
"This document was created with an earlier version of Pages. To maintain the ability to open the document with earlier versions, click Save As and choose an application version."
The options are: Save As..., Cancel, Save.
Any ideas on why this is happening, even when working with Pages '08 documents?
This just occurred to me: Maybe my templates were not upgraded along with the app, so every time I create a "new" document with an old template (even the template "Blank"), my documents would be in the old document format. Thoughts?

It's a well known tip.
On my machines, an Applescript is launched every morning which install a clean set of preferences files for the most often used programs.
Doing that, I am quite free of the kind of oddity which striked on your machine.
--(SCRIPT keepcleanprefs.app]
To keep clean preferences files.
In your userAccount's Preferences folder,
create a subfolder named "safe_Prefs"
Store in this folder clean duplicates of the preferences files subject to corruption.
Save this script as an Application Bundle where you want.
Why not in your Applications folder?
Open the System Preferences Pane "Account"
Click on the "Login" tab.
Drag and drop the script's icon onto the window to add it to the list of login items.
On every boot process, the script will be run so it will install the clean prefs.
Of course, if you change something to the prefs and know that the file is clean,
duplicate the new version to the safe_prefs folder.
