LG TinyMCE Boxes not loading

Hi,

I’ve installed the latest TinyMCE Extenion and files. It was working fine until a few days ago. The dialogue boxes (to add links) don’t load properly anymore. The box appears but there is nothing is in it, no fields or buttons. Anyone know what could be causing this?

Gzip is off.
