Minecraft inventory won't open in 360revolution

I'm attempting to mod my inventory, and I get the save on my USB and open it with Horizon then open the gamesave tool in 360 Revolutions. It says it's reading the file and eventually says complete but no list displays.
I saved the game with one cobblestone in each inventory slot and I'm able to stick the USB back in and play the game, it just doesn't open in the tool even though the bar is green and says complete.

Any ideas on what to try? Thank you.

 

I have the exact same problem, funny thing I'm using cobblestone too
