Urgent: Can't connect to Paypal

I am trying to connect my webflow Ecommerce site to Paypal, and it’s not letting me do it. It says I already have an existing Paypal account set up with that email address and to log in. Then when I click log in, either it takes me back to the same previous screen or nothing happens. This is incredibly frustrating as I can’t set up the Ecommerce site at all that we’re paying for! Please advise.

My read only site is Webflow - The Green Monster Fishing Light

Thank you in advance!
