I have purchased the xkey 360 and tried to install it, but got an error E64. I read that there is a problem with the file on the micro sd and that I need to reload the files, but when I try and format the micro sd card it wont completely erase everything off. It still says the sd card only has 117mb (its 128mb card)on it. I tried using hpusb to erase everything but it didnt work. If someone could help me out so I can reinstall the new files on this it would be great.
