Mailing sharePoint Group Users in SSIS 2005

Hi Friends,

I have a requirement to mail a group of people in SharePoint group through SSIS 2005.

I am not able to get the SharePoint Group users in SSIS 2005.

Can anyone tell me , how can i get the same?

I have already installed CodePlex's SharepointListAdapter, but while using Sharepoint List Source, it gives the following error:

"Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.SharePointListSource,
SharePointListAdapters, Version=1.2005.0.0, Culture=neutral, 
PublicKeyToken=933a2c7edf82ac1f" is not installed correctly on this computer.
(Microsoft.DataTransformationServices.Design)".

Any help will be appreciated. TIA.
