I have installed and uninstalled Squirrel 3.0.3 about 8 times in 2 different machines, but I cannot get the DB2 driver to load, although that's the only optional plug-in I'm selecting.  I need help, please.  I'm running on Windows XP Professional SP3.  I am using the installer I downloaded, which is the file "squirrel-sql-3.0.3-install.jar".  The installation goes without error and it indicates that it's installing the DB2 driver as the 3rd step, but nothing.
When I open the app all the drivers, except for "JDBC ODBC Bridge" have the red "x" icon next to them.  If I double click on either of the "IBM DB2..." drivers I get the "Change Driver" window.  The Class Name shows "COM.ibm.db2.jdbc.app.DB2Driver", but if I click "OK" I get this message on the message area:

"Could not find class COM.ibm.db2.jdbc.app.DB2Driver in neither the Java class path nor the Extra class path of the IBM DB2 App Driver driver definition:
java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver"
Am I doing something wrong?  Please advise.
