I have just downloaded the update myself, but used the prior version quite a bit. Once you add the Gauge (chart, dial, etc) to the project, go to Data | Choose Data Source (or 'Connect to Data' icon on toolbar). This will open a wizard which will guide you through selecting the type of connection and the query. If you want to change the query, you cannot not use the display box labled 'SQL Statement' at the bottom. You must use the Data | Choose Data Source selection again or the 'Connect to Data' icon on the toolbar
