Receiving this error in a WPEngine hosting environment. We do not know what triggered it but we did see that sometimes $this->nexus can be null in this function in certain instances. Added a simply null check: Error Details ============= An error of type E_ERROR was caused in line 24 of the file /nas/content/live/oursite/wp-content/plugins/taxjar-simplified-taxes-for-woocommerce/includes/class-wc-taxjar-nexus.php.

TaxJar now requires PHP 5.3+ installed, and WordPress/WooCommerce recommend even newer PHP as well under the "WooCommerce->System Status" report.
Can we fail to initialize the plugin to avoid breaking their checkout when the wrong PHP is installed?
