Importing Spirit site--none of my content is there

I tried to import a site built in Upfront with the Spirit theme to another site using the Wordpress Importer Tool. I have already activated Spirit and all the same plugins on the new site, yet it now looks like the Spirit Sample Page, with my only original content being links from my Main Menu. Am I missing a step in the Import process, or need to change some configuration on my inbound site?
Thank you for your assistance!
