installation error Fatal error: Call to undefined function: init_user_groups

[hoss]

Hello.
I am in the testing stages and trying to get PhotoPost to work with VBulletin V3.04.
I am getting the following installation error.

Fatal error: Call to undefined function: init_user_groups() in /home/httpd/vhosts/my_url_location_/photopost/install.php on line 623

can anyone offer me a hand.
Thank you for your time in this matter.
Sincerely.
Hoss
