PS4MSP Authorizations

Hi

I'm trying to use OpenPS4MSP (Version 2.02.00) for downloading project information from PS Module in SAP to MS Project 2003.

When i try to connect to SAP through PS4MSP, i am receiving and error msg stating Login Failed.

Do i need additional authorizations to access OpenPS4MSP? If so where can i find the list of transactions to which i need authorization?

Can someone provide a step by step procedure on how to setup users in OpenPS4MSP and connect to PS module?

Thanks for your inputs
