PayPal Commerce Platform button continually shows as loading

I am trying to install PayPal Commerce Platform via the Widgets > Cart & Checkout tab in Sellerdeck v 18.1.2 yet the button continually shows as loading.

I assume that this is something not right on my PC.

Any ideas?

For anyone with this issue, I solved it by de-installing Sellerdeck and re-installing it.
