SOLVED: For future reference, this is to confirm that:
1. I followed the steps in the link, and copied the three files to the specified folder. There were already files of that name there but I said Yes to overwrite them. I have opened Hybrid a few times and don't see the same "qt platform plugin" error, so I think your solution solved it.
2. I unchecked the Crop/Resize--Crop View and it solved the problem.
