Gallery Module

Hi,

I thought I'd try out the Gallery Module. But at this time, I am running 
into the following message after installing the Module when I attempt of 
access either of the Gallery Module or the Security Module:
User Error
Privileges Error
You do not have the proper security to perform this action!

Problem:
The operation you are attempting requires privileges that you do not have. 
Contact the systems/site administrator to request access.



Anyone got thoughts on what is causing this? My configuration is:

Xaraya 1.1.2

PHP 5.1.2

Gallery 0.9.7

Security 0.9.5

Ajax Lib 0.9.0

Any suggestions appreciated.

Cheers,



Wayne
