Sorry, I don't have it too.Sorry but I can't seem to find R55 file. Is there any link available for it?
Maybe someone can upload it here.
Anyway, did you try to re-install a2n app?
After that for having CPU/GPU boost, enable boost.. (but in previous app it was reversed logic)
Then you can also set input booster duration to 3000 ms to improve FPS in games.
