I'm having trouble getting the GoCardless interface working. I've downloaded the GoCardless PHP library zip file from github. However, I'm unsure where to save it, and what to name the library. The documentation does not help. When I try to pay with the "Direct Debit" option, I get a "GoCardless Library not loaded" error.
I'm using Drupal 7.37 and Commerce GoCardless 7.x-1.x-dev
I have a client waiting for their new website to go live, but cannot without the GoCardless payment working, so a speedy response would be appreciated.
Thanks, Paul
