headspace does not expand & open for page settings

I am using wp 2.8.4 and trying to set up page setting from headspace2 ,
but when I click on any link like global settings or any other of them,
they don’t expand down to let me for configuration.
this was working before but not anymore.
also I can see there is another new version of headspace2 version 3.6.16 ,but wp codex says this has not tested with 2.8.4.
does anyone use this with wp 2.8.4 ?
does it mean that I can not use this with my current WP version:2.8.4?
Thanks for any help on this issues.
