Theme is gone… stylesheet all gone

A site I’m working on got hacked with the pharma hack:

while trying to fix it, I changed the permissions on all the folders from 755 to 744.

And everything broke. I couldn’t even get into the admin until I changed it back, but now the entire theme is broken. I’ve reset all the permissions to 755, but the theme isn’t coming back.

I put the main site on a construction page, but you can see the problem here:

I moved the whole site, installed a new version of wordpress (in attempts to fix the hack too) but the theme still isn’t showing up.

Please help!!

Thank you.
