Trying to migrate a WP Install into a Site on a WP Multisite

We created a snapshot of l4b.wpengine.com (htaccess to view is demo / demo123) , imported it into the multisite my.co4.com, now are trying to import it into a subsite loansforbullion.my.co4.com (mapped as loansforbullion.ca). When running an import, it says it's done (although runs in 1 or 2 seconds) and then, nothing happens. I've imported into this multisite before, what did I miss?
