I am also getting Error 601. I live in Korea but my account is NA and my credit card is from the USA. I am also a 1.0 user. My subscription ran out so I went to update the payment info, and bam 601. I've tried adding crysta through paypal and game cards like people suggested but SE still not accepting it. I tried to use the Live Chat but after 2 hours of waiting I finally got to 5 in the queue, and it said no one is available and kicked me off. Are you kidding me? What kind of customer service is that. I've tried different browsers, I've tried changing my IP to match my card, I've tried multiple different payment options, still Error 601. I've called my bank to see if it was on their end, and it's not. Seriously SE, you have to wait 30 days? If that is the case, you just lost another subscriber. WORST CUSTOMER SERVICE EVER. (let me just make an international call to your support number and sit on hold for an hour and enjoy my nice phone bill for you to tell me there is nothing you can do.)
