I am using 732 and got the "keypad lights only glow" problem. I have downloaded VPCT.rar, VIA_CBP_USB_Driver.rar and iT806C_731 many times. But there is problem with the integrity of those archives and their headers are corrupt. I can extract them but cannot get the program running. I have searched for the same files on net but can't find them. So, where can I get those files intact or can somebody please repost them or help in some other way. If anybody has backup copies of them please help.
