Site Importer Tool Not Working - AEM

Hello,

I have a new instance of AEM 6.1 running (I'm new to AEM) and have followed the Site Importer guide:  https://docs.adobe.com/docs/en/aem/6-1/develop/dev-tools/site-importer.html.  When I click run the importer's progress bar endlessly refreshes, and the process is hung up at 'creating design.'  Is there a pre-configuration requirement, or some other step(s) I should be looking at in order to get this to work?  Here are the steps I followed:

1. Open importer
2. Populate project title
3. Populate site URL
4. Add thumbnail image
5. Tick overwrite
6. Click 'import site'
7. *Note:  I skipped 'sitemap' and extend from component'

Thanks in advance!
