[Plugin: Email Users] Can't see individual users since upgrade

Thanks for the update. I have installed the update but still can not email individual users. Looking at the source of the page I see this:

<select name=”send_users[]” multiple=”yes” size=”8″ style=”width: 400px; height: 250px;”>
</select>
so I get the box but no users to select.

I was unable to get this functionality back so have switched to http://wordpress.org/extend/plugins/emu2-email-users-2/ which has brought back the functionality for me.
