404!

Hello.
I’m trying to do a site with wordpress.
-i’m in local
-started from the classic template (by dave shea)
-changed only the stylesheets inside style.css
-now i’ve a template like i would,

Problems:

when i write an article, or a page, i can see only the links in the homepage, if i try to click on these, i’ll receive always ‘404: page not found’!!

It’s the first time that i receive this error.

Dunno what could be that caused problems!

I need help, then, really help.

Waiting for an answer, i give you my respect for this nice work making wordpress.

Thanks to all.
