When I registered, it prompted that my email address has been registered, the email address is yukui0520@hotmail.com, then I changed my Gamil mailbox, it still prompts to be registered, I am very sure that I have never registered serv00 before, can you help me check, and one more thing, I used another email address to register successfully, however, I did not find it in the email, including junk can, advertising emails, etc., I waited for nearly 1 hour for this
