I found the bug that blocked YourHead's Collage 2 from working in Internet Explorer 9. You can read about it at, and download the corrected plug-in from, the YourHead Support Forum. I attached it there to my last response. If you can't download it from there, contact me and I'll mail you the 2MB zipped file.
Do not 'install' the unzipped file. Rather copy it to /Users/YOURNAME/Library/Application Support/RapidWeaver/
You can open your 'Library' folder, if you do not see it, like described here: https://www.macworld.com/article/1161156/view_library_folder_in_lion.html
