I also thought pressing menu button accidently would be the cause and after you told me to change keynote's preference, I can even see if im having menu screen on or not..

however that is not the issue..

basically only buttons from my remote that works for my keynote are FWD and RW buttons to move slide back and forth...

if i press play button, nothing happens.. 
if i hold pressing play button again, nothing happens..

for other keys, nothing happens...

(of course if i press menu, it pops up)

hm...

what would be the cuase? 
i tried to delete and reinstall too 
but didnt solve the issue help me plz
