Hi all…

I am helping a colleague to use PsychoPy and she had her experiment all up and running but today when she tried to open the file it will not open. It starts to open PsychoPy but then ‘PsychoPy2 Error’ appears and it shuts down. This is using PsychoPy2 on Mac - version 1.84.1.

The experiment does open and run in coder but just not in builder.

Below are the logs from console. They mean nothing to me but maybe they might shed light on the issue to one of you.

Thanks  
Matt

I notice that I can actually open the file from within Builder and it then runs but the GUI doesnt show any of the loops and routines and at it just looks like a new and untitled experiment file. But when I click run it actually runs the experiment. It does mean that I cannot edit the file though.

It also appears this person is having the same issue:

This is a duplicate of the issue below. I’ve posted the fix at the bottom of that thread.

> We think this was caused by renaming a Routine; this was a new feature and apparently not working correctly as of 1.84.1. The bug that led to this issue is now fixed and will be included in next release (1.84.2). For anyone else having this issue you can fix your file manually like this (make a copy of your experiment first in case you really mess it up!): open your .psyexp file in a text editor (e.g. notepad+ on windows, textwrangler on mac) near the bottom of the file you’ll see a section d…
