继续死嗑softube，写了一封写给他们的客服，回信说：This is David at the Softube Support. Thanks for reaching out!
This could be due to the "new" EU regulations regarding online payments. Please see the info below:
An added security step for online payments
On September 14th, 2019, the EU brought to life a new regulation to make online payments even safer. Following this, a new procedure called Strong Customer Authentication (SCA) was developed and made a requirement of the EU revised Directive of Payment Services. Naturally, we have updated our website to comply with the new regulations.
What does this mean, and can I prepare?
From now on, you are more secure when buying your high-end plug-ins (and probably other things, but what could you possibly need besides plug-ins?) in an online store like ours. When completing a purchase, there will be an extra security step to confirm your identity to your bank.
One way to prepare for this is to make sure your bank has your most up-to-date personal details. Digital wallets like PayPal are already set up according to the SCA-regulations, so you can keep using them without a worry.
Also make sure that your Softube account is set up with your correct details, matching your card.
这可能是由于欧盟有关在线支付的“新”法规。请参阅以下信息：
增加了在线支付的安全步骤
2019年9月14日，欧盟出台了一项新法规，旨在使在线支付更加安全。在此之后，一个称为强客户认证（SCA）的新程序被开发出来，并成为欧盟修订后的支付服务指令的一个要求。当然，我们已经更新了我们的网站，以符合新规定。
这是什么意思，我能准备一下吗？
你现在可能需要更多的插件吗像我们这样的网上商店。完成购买后，将有一个额外的安全步骤，以确认您的银行身份。
为此做准备的一个方法是确保您的银行拥有最新的个人信息。像PayPal这样的数字钱包已经根据SCA法规设置好了，所以您可以继续使用它们而不必担心。
此外，请确保您的Softube帐户设置了正确的详细信息，与您的卡相匹配。（百度机翻）
还是没有搞定！找了里外一个朋友，也是一样的问题
