Broken game

Hello, i was compiling a game from android today, and it was taking ages on compiling. After about 45 minutes i looked in the log viewer and it showed nothing from the last half an hour, so i clicked exit stencyl and then saved. I then opened up stencyl and tried again. This time it worked, but the app on my tablet would open, and then say "unfortunately My Game has stopped".  i then tried running on flash player and got the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

i also got the error could not load collision groups -2 and 3 in the log viewer

Then i tried to test game in windows (debug and non-debug mode) and it got stuck on compiling.

Then i tried android debug mode and it got stuck on compiling.

I then came to the conclusion that my game is probably broken, so i looked it up and i found that i should attach the game folder
as well, which is now attached

P.S    Make sure you use a file viewer like 7-zip to see the files that cant be viewed in the standard windows file viewer

Might have not put a value in - I've found stencyl can be bad at informing you where those are. It makes a line red way after the absent value.

First step : Check your new code and see if you've not filled in a value somewhere.

No, everything is filled in with values

i fixed it!!!!!
I will be posting a video on youtube in a few days showing everyone how to fix broken stencyl games!!!!!!!!
