Multicurency Plugin for Woocommerce v3.3.5

I installed multi currency the free version which worked with the WordPress v4.9.4 and Woocommerce v3.3.5, But after purchasing the premium version i realised it does not work with the WordPress 4.9.4 and am not ready to update the WordPress since the current theme and setup will be largely affected. Is it possible that you can get me the plugin version that will be compatible with my WordPress and Woocommerce version?
Your help will be much appreciated, thank you.
