Dreamweaver CS3 Reinstall with no disc :s

I'm not sure how it happened, but I can't seem to find my disc for my copy of
Dreamweaver CS3.

I went to install it onto my laptop but I opened the box and there was no
disc. I have a legal serial number, but everywhere I look there's only
downloads for CS4 and none for CS3.

Anyone have any ideas? I only need the installer portion...

Grab just about any book on Dreamweaver CS3. They almost always come with a disc that includes the 30-day trial. When prompted for the serial number enter your own and you're good to go.

I've been needing to get a book, anyway...
THANK YOU :'D
Muchly appreciated
