paypal isn’t working

I’m new to Probux, but when trying to use the paypal link icon in probox, it gave me error message “Upgrade purchase via Paypal is temporarily unavailable, please use another processor.” Well I’ve been trying for the past couple days at different time, even at 00:00:00 server time, and it still doesn’t work! The only other option is to use Payza. paypal isn't working well never work really paypal isn’t working well never work really
