First mod tutorial - game won't load, stuck at 40% loading

[alleycat 135]

Attempted to complete the "first mod" tutorial. However the game won't load.

It packed without script errors. All files mentioned were created and the code pasted from the tutorial.

Then I set up a batch file with the path:

......DayZDiag_x64.exe -mission=pathToMission\myMission.ChernarusPlus -mod=P:\FirstModPacked


When loading, the load bar gets stuck at 40%
