Hi , New to this so hope am posting right, I have a zgemma h2s , after a few days I lost the epg listings , I've left it on overnight for updates and when I try to go into crossepg "download now" I get an error message saying no NIM no. I haven't made a favourite channel list , about 5 freeview channels came up this morning with full listings with all others still blank. If I click on a channel and then go back into epg the program will appear on it then , would be grateful for any help , g
