Hi Joe,
Thanks for reaching out.
Sorry to hear about the issue.
Please take a full backup of your website first.
Then, try uninstalling all instances of SP Page Builder from your site and reinstalling a freshly downloaded copy through System → Install → Extensions. This usually resolves issues caused by missing database tables.
If the problem persists, it may be because the installer cannot find the missing table. In that case, creating a basic (dummy) version of the missing #__sppagebuilder_versions table manually can allow the installer to recognize its existence and complete the installation properly.

If you're still unable to resolve the issue, please share FTP/database access so we can investigate it further.
Best regards,
