I missed your post because it was posted as a forum topic instead of a support ticket.
The 1.6 version is experimental one and was withdrawn from extensions.joomla.org until it will be fully tested.
I installed the version on codegravitydemo.com - it runs on joomla 1.6 and it works without any problems.
I would like to know why do you get this blank screen. Could you please help me to find the solution to your issue ?
