A different elm-format crash

[ScribblerWriter]

When I save an .elm file, formatting isn’t happening, and in the console I get the following error:

Sublime Text 3 elm 0.19 I’ve got “Elm Language Support” in the “install_prereleases” section I’ve upgraded the package

Error loading scope:source.glsl: Unable to find syntax file for scope source.glsl in Packages/Elm Language Support/Syntaxes/Elm.sublime-syntax
Traceback (most recent call last):
  File “./python3.3/subprocess.py”, line 1104, in _execute_child
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File “C:\Program Files\Sublime Text 3\sublime_plugin.py”, line 1072, in run_
    return self.run(edit)
  File “C:\Users\Chris\AppData\Roaming\Sublime Text 3\Installed Packages\Elm Language Support.sublime-package\elm_format.py”, line 33, in run

  File “./python3.3/subprocess.py”, line 1110, in _execute_child
FileNotFoundError: [WinError 2] The system cannot find the file specified

This was working fine until a few days ago, when the formatting just suddenly stopped working. I haven’t made any changes to my Sublime Text configuration, nor to where elm-format is stored. I’ve checked and made sure that elm-format is still in the path.

Source coloring, compiling and auto-completion seem all to work fine.

I’ve tried reinstalling Elm Language Support, elm-format, tried downloading ELS from the github repository into the Packages folder, but with no success.
