I'm hoping someone can shed some light on a weird error I'm getting when attempting to compile my projects on a new PC.
All of my projects are stored on Dropbox and are compiling successfully on other machines.
But on my new laptop (a Dell Inspiron running Windows 10 with a fresh install of Therion 5.5.7) I am getting the same error every time, across all projects. It appears to be some issue with Metapost and/or Tex (neither of which I really understand to be honest). Here's the relevant bit of the log:

The two files given above are one of your source files
and an auxiliary file I need to read to find out what your
btex..etex blocks mean. If you don't know why I had trouble,
try running it manually through MPtoTeX, TeX, and DVItoMP
