CURCY error taking my website down daily

Hello,

I have been using your CURCY plugin on my WooCommerce website mylarshop.com for over a year.

Recently the site has been down frequently, at the same time each time. The issue seems to be a fatal error when trying to update the exchange rates.

I recently purchased the paid for version of CURCY, to try to fix the issue. I entered the product key on my website, but it’s still showing as ‘Verifying Key’ after over a week. Could you please verify the key, or explain what I need to do to stop this plugin taking down my website daily?

Thanks,
William
