Jquery plugin problem

I’m using lightbox 0.5 plugin for jquery in my site, the problem is - it’s using quite old version of jquery and with the newer version plugin doesn’t want to work. Maybe someone knows how to fix this problem? Or maybe i should stick with the 1.2.4v instead of 1.4, is there any noticeable difference?

http://leandrovieira.com/projects/jquery/lightbox/ has a Changelog section that shows you what improvements have occurred to the plugin.
