Migrating a site with Snapshot Pro

Hi, trying to migrate a snapshot from dev.danahersecuritysystems.ie to danahersecuritysystems.ie. I have succeeded in importing the snapshot but when I hit the 'restore' button below the snapshot, the page refreshes and shows the snapshot with 'Archives: Pending' as the status on the right and I can't do anything with it. I can't post the screenshot here. I did all of this last night but it is still the same this morning. Can you help please?
