Aw crap I made it also... mine is 58 ....
check here
I did test mine in game and it works.
If yours is 56 that means that you used 14 bytes of null data? How did you came with that one?
I used 16 just to make sure it is power of 2 friendly...
EDIT:
PS: I think you uploaded the wrong files. (there is one 44KB and one 82b in the zip)
