Captivate Characters from previous releases missing

I use avatars in my projects frequently. I've recently upgraded to Captivate 2019 and none of my characters are showing available.

I've tried using the solution here: https://helpx.adobe.com/captivate/kb/captivate-2019-update-2-faq.html but that did not work. My 11_0 folder does not have an images subfolder, only the business, medicine, casual, etc, folders, and moving those to the Assets folder for 11_5 did nothing.

I also tried the solution here: https://community.adobe.com/t5/captivate/problem-downloading-assets-in-new-11-5-0-version/td-p/10505584?page=1 but that does not work. I don't have this available to me: C:\Program Files\Adobe\Adobe Captivate 2019 x64\utils\CleanPreferencesWin.bat ; the Adobe folder does not have an Adobe Captivate 2019 x64 subfolder even when I view hidden files. 

I'm a complete loss right now and I'm very frustrated. Please help, thnx.
