我下载了客户端的安装程序，但是还没有输入cd-key。然后今天和昨天换了一个IP环境想要输入cd-key，但是却提示了：“Based upon recent suspicious activity, we have identified that your account may potentially be at risk. For your protection, we have temporarily suspended login access to this account.
Instructions for lifting this restriction have been sent to the email address registered to your Square Enix Account.”
说是要给我的注册邮箱发个邮件去解决这件事，当时注册的时候没多想就直接用了163邮箱，看到SE账号的注册的时候发的邮件是可以非常迅速地收到的就一直用了。
可是现在一直收不到给我发的邮件，请问我是应该换个账号并且换个邮箱么？我看gmail也上不去啊，有什么好的邮箱推荐么？
