Saldly Rise of Darkness didnt work at my COmputer at all. (HUD was missing and after over 30 Minutes still processing Turn 1 I needed to reset my Computer to do anything)
I had the HUD missing issue as well - tabbing to desktop cleared that. The main problem i had was that it needs a fresh install from FfH 41d and you need to run a "Play now" as well to clear options.
