WP 3.5 Visual Editor Broken, Can't Insert Media, No Editing Tools

Hello,

I’ve just upgraded to WP 3.5 from 3.4.2 and have the following issues:
-When editing a post, the visual tab doesn’t go anywhere, it’s there, I can click it, but it doesn’t load any changes.

-I can click “Add Media”, it’ll pop the media manager (which is a beautiful improvement), I can upload a file, it’ll show up correctly, but when I click “Insert Into Post” nothing happens, but it returns me to the line in the post where I was editing, but no code.

-If I click “Media” and enter the media manager, and then click “View”, it’ll launch a page (https://www.sector67.org/blog/?attachment_id=1924 for instance), but the image won’t be there. If I copy target URL and paste it into the browser it’ll show up (https://www.sector67.org/blog/wp-content/uploads/2012/12/laser-cut-house-1-4-width-1024×662.png)

-There’s no tool box at the top of the edit post area. Usually there’s a variety of tools (at least there was previously), was this lost in the new version or is this also broken from my installation?

Troubleshooting steps I’ve taken:
-Disable *all* plugins, didn’t show any improvement so I re-enabled them.
-Install and test Twenty Eleven or Twenty Twelve, also disabled plugins, no improvements.

Any other ideas? My next step was going to be manually copying over all of the files for the installation to see if something was mangled on the installation the first time.
