Problem with plugin

I uploaded a Widget importer and exporter plugin. No Problem. When I went to upload a widget.zip file I got the following msg: You must upload a .wie file generated by this plugin. Not sure what that means or how to go about fixing this issue.
Thanks

Hey @cisco7819, Welcome to the community!

Looks like it could be something with the .wie file type. Found this similar thread from the widget importer and exporter plugin support page:

Might be worth reaching out to their support about this.
