When i try to check out with my live stripe recurring

When i try to check out with my live stripe recurring gateway for memberpro, i get the following error after entering payment and submitting. Fatal error: Cannot redeclare class Stripe in /home2/videowoop/public_html/wp-content/plugins/membership/lib/stripe-php/lib/Stripe/Stripe.php on line 4
and the payment states pending in memberpro2 . Stripe is set to live with correct api credentials, and i tried both ssl and non ssl checkouts, same error.
