I tried to donate $50 with paypal to gain VIP, but the site is giving me the error "Invalid receiver_email. ([email protected]) " in the donation review.

It tells me on PayPal that the money has been sent, so do I need to wait it out a bit for the website to do it's thing or does something else need to happen?

Thanks for reporting, we are checking the issue and will provide you an update soon.

EDIT: Problem is fixed.
