Cannot login after payment

Hello,

I've just paid for the lifetime membership at https://nomadlist.com/, and received the receipt from Stripe with my email account. However, I cannot login with that email account. The site stated that my email is not registered in the system. I've also checked the steps listed in https://nomadlist.com/faq#cannot_login but it doesn't provide solution to my problem. Also tried to contact no-reply@nomadlist.com but that email address does not exist. Wonder if anyone can help.

Many thanks
