Hi Bob,
Try this for the connection string:
<add key="MSSQLConnectionString"
value="server=sql.prw.net;UID=whitestarpr;PWD=yourPassword;database=whitestarpr" />
They're saying you can use ODBC but if the application doesn't support ODBC, you can use the info they provided.
Let me know if that connection string doesn't work.
HTH,
Joe D.
