Not able to connect sap thru openps

Dear Gurus,

I have installed MS Project 2010 - professional and also installed  OpenPS_for_MS_Project_4.0 and applied  OPENPS4MSP04P_4-20005295. When I am trying to connect with SAP  on both group server and custom application server connection type  giving all the required parameters, system shows logon failed.

System.Runtime.InteropServices.COMException (0x800A0CC1): Item cannot be found in the collection corresponding to the requested name or ordinal.
