i had this problem also. when i phoned the help line i was told to switch off power wait a little while and switch back on and then to highlight the programme above the one i wanted to delete and then
VERY QUICKLY IN QUICK SUCCESSION cursor down, press blue button and then the green button. If nothing happens switch off power wait a little while ,switch back on and hopefully on re-boot it will have gone. I hope this works for you it did for me.
