Ok I checked it and the file is definitively corrupted. I sent it to an emulator and it plays fine (and is 16 KB on-calc) but on my PC it says it's 192 KB and Flash apps are normally up to twice their calc size on the computer (so it should not be more than 32 KB). What OS did you use? It's possible you'll have to poke the author himself directly about it.
EDIT: You could try doing a manual Garbage Collect before sending the game, then try sending it again to see if that works. Or maybe do a full memory reset (back up all your files first, of course).
