CCS v3.3 is not supported on Windows 8. Support for this particular revision was last on Windows XP.
You can download the latest version (v5.5) from here;

This board, emulator, and chipset are all supported by CCSv5.5 and since you're using an ezdsp kit, you will be able to use the "free license" option.
