To answer both your questions:
Cannot read TOC -> get rid of that image. It's bad. I had one too a few weeks ago (Wild 9 in the YSI thread)
To get Chankast stay in english.
1) uncheck the read-only box in the file properties of DC_Bios and DC_Flash
2) run chankast w/o a mounted CD so you go to the bios menu.
3) go in options and select english.
4) exit that menu and return to the main menu screen.
5) quit/close Chankast.
6) check the read-only box in the file properties of DC_Bios and DC_Flash
Both these files are now locked in English mode
