i have the 360usb kit hooked up to my dvd drive hooked up to my pc. My pc gave the drive a letter and it shows it in "my computer". I have maximus extreme 2.3 but when i go to folder x-lg and right click when i go down to "open command window here" i get a message saying "another program is using this file". I have two questions. why does it say that and if i can't flash it that way can flash it thru the start>run way? I am almost there i can taste it so can someone please help?
