did it by isdn yesterday and it stopped at exactly 33% !
i was that scared after reading this post and having the same problem the day after...
waitet 10 min and it jumped to 46% and my heart jumped so high you can't guess how i felt in this moment, i danced in my room and i was actually singing !!!!!
it worked well after this...
PS: i had this one but didn't play it half a year ago so couldn't remember
