Website builder

I want a good free site builder and I have used yahoo and liked it.

Okay this might sound confusing so i will explain it as best as possible.

My laptop crashed because of stupid photoshop
And i have been using photoshop elements five when it crashed.
I was also using yahoo site builder to build my website. So I lost everything when i had to totally recover my computer. So you can still view the site, but i dont have any of the templates I made with the site.
Is there a way that i can pull the templates off my website and save them on my computer so I dont have to restart my whole website project?
but when i recovered my computer (basically uninstalled everything) nothing is there. Soo…… i am wondering if on the site that i can somehow get everything from there and save on my computer so i dont have to start all over.
Nevermind!!!! Called tech support. Thanks !!!

I need to change one of my yahoo hosted web pages, but no longer have the web builder software installed on my computer
