Epg not showing

hi guys - i have a genuine vu+duo reciever, ive always used the opentv provider as my epg which is downloaded to my 1 Gb Kingston USB stick along with picons that i have installed on the usb stick. I Noticed all of a sudden that the epg was not showing anymore, so i downloaded again , goes through the motions of downloading the epg but it doesnt populate anymore, i have reformatted usb stick, and have even tried to download to the hard drive but the epg just doesnt show up. I have tried freshly installed Bh images from 2.0.5 to the latest 2.0.9 and all give me the same result, ive tried a different usb stick as well, ive also tried the rytec providers which appear to download but the epg just doenst populate...any ideas why.
