Can't update a hog III to the latest sofware

Hi everyone
I'm trying to upgrade a hog III to the latest softaware but it seems like it gets stuck after confirming I want to update and delete all shows on the console. I've burnt my CD with my macbook pro like I did many other times. I reburnt the CD a couple of times now but no luck at all.
I can't even boot up the console normally for the previous software has been kind of corrupted! what shall I do?
Thanks a lot
Marco
