i think it's the cable problem,i've heard many ppl said lik-sang cable **** " upload is ok but dowbload not! http://tools.geocities.co.jp/Playtown/2004/@geoboard/515.html
the only things i can suggest u was try download the rambooster,it's a freeware to free up yr pc memory,it's useful when ripping g**e, it can prevent hang up after a fews hour ripping and prevent the tterm stop without reason "at least for me"
also turn off program like anti virus,getright ,sw joystick and don't try to use other program or access internet when ripping
sorry for my bad english,i hopes this can help
