when you try get paid to coinbase address then it works.
but when you use other aadress this happens: http://gyazo.com/bb84f4a30f8c5054fe9e645e75736cda

also, yesterday when I installed this script it worked (with coinbase aadress), but today it shows server balance 0 satoshis, although the actual balance is is 130k satoshis and can`t cashout with coinbase aadress (An error has occured - Status code 403).

so right now it is not useful.
