It seems you’re using Nginx server? If that is the case, please proceed testing with Apache instead as our Lite version does not support Nginx yet.
Also please note our Lite version is available for Magento 2.0.7 only.
PS. The Lite version is aimed at helping you have a close look into the migration process as a test project. It provides you limited features, compared to our latest Pro version. You can learn more on the Pro version via this video: https://www.ubertheme.com/magento2/ub-data-migration-pro-v3/
