SQL Server 2005 Data Source

I'm trying to use SQL Server 2005 as the data source without success. I'm using a trial license with ver 5.0.2.0 and when I open the File|Data Sources window, I'm not given the opportunity to add a new data source. The screen allwos me to select SQL Server or Access, to Edit, or to Set as Default only.

Also, I was wondering if the new version would allow me to delete a group of sessions from the All Sessions tree view. The only way to delete a group in this version seems to be to delete all of the sessions inside of that group.

Thanks

Excellent product btw!
