Hello, I am trying to upload my experiment to Pavlovia from PsychoPy.  
After logging in, and closing the tab, this error shows up and I can’t do anything after.

After closing the prompt, I can’t press [Pavlovia.org](http://Pavlovia.org) \> New… either.

I have reopened PsychoPy multiple times.  
What am I doing wrong?  
I really appreciate your help.
