I'm not a coder- but I don't know what installing a language pack could do to cause it... All I could come up with is:
* 3.6 version of vB : Don't forget SECURITYTOKEN modification as explained in install instructions
* Check that you haven't any non reverted chatbox templates (one that you might have modified)
* Refresh your browser cache
edit: I see a chat working on your site... maybe they're not compatible?
