I downloaded this app: https://www.odoo.com/apps/modules/master/payment_stripe/

As soon as I try to install it I get this traceback:

```2016-05-20 13:07:41,702 5853 CRITICAL admin openerp.modules.module: Couldn't load module payment_stripe

I'm on the most up-to-date version of Odoo. Is there some reason this isn't working??
