Can someone please shine some light on this occurrence

I am in KEFALONIA with vu duo 2 and 1.5m dish

Yesterday all my channels on 28.2 which are not FTA have gone to a black screen and these Are not HD as I know HD has a black screen

I can still access other satelites which aren't FTA s I I know it's not a software problem but anything on 28.2 just gives a black screen

Sorry if this thread appears twice as it disappeared so retyped

Many thanks in advance
