Yes, this fixed it. But even though it doesn't throw an error anymore, I still haven't managed to get it working.
As far as I understand, I just need to copy the file into the game directory of the VN, then use the `Check Script (Lint)` option from within the SDK, right?
Well, it keeps giving me the standard condensed statistics output.
e.g.
Statistics:
The game contains 7,634 dialogue blocks, containing 53,666 words and 289,170
characters, for an average of 7.0 words and 38 characters per block.
The game contains 71 menus, 21 images, and 37 screens.

EDIT: Hmmm, my projects folder is outside of the SDK, obviously... But when I copy the file into the Tutorial's or The Question's game folder (inside the SDK structure), it works...
