iWeb suddenly not publishing

I have 3 websites - my personal site and 2 client sites which have passwords on them. Thanks to Finder have the mother of all freezes I've spent the weekend reinstalling everything back onto my Mac Pro, and when I transfered my iWeb domain file from the back up to the iWeb folder in App Support, as expected it needed to republish everything.

That was fine for the two client sites (with around 60 mp3s on one and 15 on the other) but now when it comes to publishing my main site (with one change - an icon has increased in size) I click on the publish button which greys out... and that's it. Nothing else happens. The spin-ey thing doesn't spin next to the site. It just sits there idley doing sweet nothing.

I've logged out of my .mac account and back in again, still nothing.

I've heard about people saying that it won't publish changes, but this won't publish period! (I've just added a blank page and it's doing the same thing)

Any ideas?
