Had my duo ages now and upgraded to vti 4.1 the other day because until a week ago the box was booting fine with a wif dongle and a usb stick in the rear with epg & picons on but now it will now go past reading usb until i take out the isb containing picons & epg ive installed nothing new , removed nothing ,have not formatted stick .
Just will not go past reading usb until i remove it , so what has changed

thanx in advance
