is the newcam.list file you have the one provided to you? if so, you just ftp that into the usr/keys folder, replacing the newcam.list file that's already in the operating system of your receiver.
then exit everything - blue button, select softcam manager, select softcam and scroll across to mg.cam 1.35 (or 1.38) - restart cam (by using button choices shown across bottom of screen, think its the green button?)
