I did. But it says it's missing a line. I downloaded the most recent version.
But it says it’s missing a line.
What says what is missing a line? The error message you showed (three times) is about syntax error. That error usually happens when Python 2 code is being run on a Python 3 runtime.
I downloaded the most recent version.
Most recent version of what?
If it is Joiplay or Renpy Plugin, like I wrote twice you should not download the latest version but version 7.7.1.
