Correction: It was the Personal version I got. Still not working.

You can read here in 'Upgrade free version to "PRO" version' section how to update free version to PRO:

Just uninstall "ARI Stream Quiz" free version and then install "ARI Stream Quiz PRO". All quizzes from free version will be available in PRO version and all shortcodes will work fine in PRO version.

If you need more assistance or have other questions, let us know.

Thank you. I went to the page shown in the instructions, but I have no auto update option as it shows. Here is the entire page where it says to go.

You don't have "Auto-update" option because free version is installed on your site. This option is available in PRO version to get updates for PRO version.

Please read instructions from 'Upgrade free version to "PRO" version' section. It mentions to uninstall free version and then install PRO version. For this open "Plugins -> Installed Plugins" page on WordPress backend, click "Deactivate" and then "Uninstall" links for "ARI Stream Quiz" plugin. After this open "Plugins -> Add New" page, click "Upload Plugin" button and install PRO version (use ari-stream-quiz-pro.zip archive). After this activate the plugin.

It also says to delete the free version and download the Pro version, but when I search this is all I find.

I had tried to upload the zip before, and gotten an error message. I just tried again and it worked. No idea what that was about. Thank you for being patient with me. This is all new to me.
