ok so i had problem with an e200 and bought a express just for a short time I hook it up to my computer at home everything is fine its working im downloading music from cds and napster only no limewire or anything else. Then i let it charge overnight next day wake up first it wont turn on its goes to the sandisk logo and thats it I plug it into my computer and say device driver not successfully installed. I cant download the firmware caus eits not on msc or watever and cant change it cause the stupid thing wont even turn on. What can I do so I can at least format the thing and try to get it working again?
