[Shipper Pro] Shipper error

I am receiving an error when I try to access the "Migrate" tab of Shipper on a fresh install of the receiving Wordpress. I tried removing and reinstalling the plugin and have removed all over plugins except WPMU DEV.

Parse error: syntax error, unexpected T_VARIABLE in phar:///home/content/19/9046919/html/cares/wp-content/plugins/shipper/lib/aws/sdk-v3.phar/Aws/functions.php on line 36
