Did anybody else's copy of Flashchat 6 stop working when they upgraded to 4.0.8? Mine did

Now everybody (including me) gets a white empty box when they visit the Flashchat link, and it is coming up "Flashchat does not appear to be correctly installed." in the WGO box.
Any suggestions on how to fix this would very much be appreciated!! I definitely haven't altered anything Flashchat related for a long time, so it definitely appears to be related to the forum upgrade.
