Import workflow error

A coworker of mine is receiving an error when attempting to import a workflow I exported.

The error message is:


The workflow consists of 3 model readers and 3 decision tree viewers, not very complicated or big. My coworker has tried importing with a new name as well as overwrigin the existing project. I have tried importing on my machine and another but cannot reproduce. Any ideas?

This looks like an error in the ZIP archive. Can you extract the ZIP file with a standard unzipper?

We never did figure this out as I updated the workflow with new data and exported it. That one she was able to open just fine.
