JDBC Driver not found when setting up connection in Crystal Reports

I have downloaded a trial of Crystal Reports to my Windows 7 Profession 64 bit machine and I cannot get the JDBC connection to find my driver. I opened a new report and am following the Standard Report Creation Wizard. In the Data screen, I am expanding Create New Connection and double clicking on JDBC (JNDI). Once I enter my parameters and click finish, I get the error "Failed to open the connection. Details: JDBC driver not found."

I have followed the instructions to add the path to the .jar file within CRConfig.xml, and I have tried to add it to my CLASSPATH environment variable as well.

When setting up the connection through the GUI, I have entered the following information in the following fields:

Connection URL: jdbc:postgresql://<our url>

Database Classname: org.postgresql.Driver

My CLASSPATH contains the following path: C:\Program Files (x86)\Business Objects\Common\4.0\java\lib\external\postgresql-8.2-511.jdbc4.jar

CRConfig.xml has the following CLASSPATH information:

C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/crlovmanifest.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/CRLOVExternal.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/CRDBJDBCServer.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/CRDBXMLServer.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/CRDBJavaBeansServer.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/external/CRDBXMLExternal.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/external/log4j.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/CRDBSForceServer.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/external/CRDBSForceExternal.jar;C:\Program Files (x86)\Business Objects\Common\4.0\java/lib/external/postgresql-8.2-511.jdbc4.jar;${CLASSPATH}
