I'm guessing 'no suitable driver' errors, see here: http://www.dbvis.com/doc/microsoft-sql-server-database-drivers/ (or look in the help from where you downloaded the driver).
The driver path seems mixed up and your connection string doesn't look kosher either.
Also search the forum for insight on security (mixed mode) and make sure your SQL Server has static ports instead of dynamic, or else the 1433 won't work.
