TI has an updated version of UltraLibrarian Free Reader (version 5.3.409) which I used to translate the TMS320C6455_GTZ_697.bxl to Altium version 10.890.23450. The exported files are included for your convenience:

I will let you know when the updated version of the new UltraLibrarian Free Reader is available on ti.com for download.
Regards,
Janet
