I am entitled to change the region code on my PowerBook DVD player for a fifth and final time. My window even tells me "this is the last time you'll be able to change your region code". Fine. But when I click to make the change, I get a new window that says There was a problem changing your region code. Error message -70001 And it happens every single time. I've looked all over for a meaning to this error message, but can't find one. Any help?
