Error for IE8 users after buddypress-fun theme update.

I recently updated my BuddyPress Fun theme and since the update I have been getting reports from users that are using IE8 that they can't get to my website. They get the following error in the address bar: res://ieframe.dll/acr_error.htm#bravegirlsclub.com,http://bravegirlsclub.com/

I saw that there was an update in version 1.4.2 for an IE8 problem, but this seems to be when the problem started for me... wondering if that update might have a bug? Anybody else having this problem?
