After digging out an old but good K800i (red53) I just couldn't get it unlocked. I followed this and a few other similar threads until I realised I was failing due to habit.
I always used to and did exit Far with the obvious exit button. But in the end I tried backing out with the "", as mentioned in a few places. and lo and behold the executor didn't disappear (as it had been) but appeared in games as it was supposed to.
Plain sailing from there.
