The free ophcrack tables only support alpha-numeric passwords. If you want to crack passwords with any system32 characters, you'll either have to buy those tables or get them off the Pirate Bay. ophcrack only supports tables made by objectif security.
If you want better Rainbow Table software than ophcrack, try http://www.freerainbowtables.com/. They have free tables for most hash encryptions, and with many sizes. The original project can be found at http://www.antsight.com/zsl/rainbowcrack/.
Unfortunately, there are no seeders for the Hak5 tables, so there is currently no way to get them.
