I precisely followed all of the installation instructions, twice, and still ran into the same problem.

When everything was updated and I attempted to log into the admin, the menu would not load correctly causing the rest of the admin not to load. It ended up being an issue with the updates required for the files admin/includes/boxes/catalog.php and admin/includes/boxes/reports.php

For admin/includes/boxes/catalog.php the update should should be,

//kgt - discount coupons
'' . BOX_CATALOG_PRODUCTS_EXPECTED . '
' .
'' . BOX_CATALOG_DISCOUNT_COUPONS . '' );
/***************
'' . BOX_CATALOG_PRODUCTS_EXPECTED . '' );
***************/
//end kgt - discount coupons

For admin/includes/boxes/reports.php the update should should be,

//kgt - discount coupons report
'' . BOX_REPORTS_ORDERS_TOTAL . '
' .
'' . BOX_REPORTS_DISCOUNT_COUPONS . '');
/*************
'' . BOX_REPORTS_ORDERS_TOTAL . '');
*************/
//end kgt - discount coupons report

Both instances were missing a period after the first updated piece of code with the link. It caused the rest of the code to not execute.
