Fatal error on activating Hummingbird plugin

When I try to activate the plugin I got this error:

Fatal error: Wrong parameters for Exception([string $exception [, long $code ]]) in C:domainskowalski-smids-vertaaldiensten.nlwwwrootwp-contentpluginswp-hummingbirdcoreapiclass-wp-hummingbird-api-exception.php on line 13

I want to test this plugin and compare the speed. Can someone help me with this issue?

Best regards Marcin
