If your UKEY is lost, for security reasons, it is recommended that you first select "Void Certificate" in the professional login interface to void your professional certificate (both file certificate and mobile certificate interfaces are used to void). Invalid success. No computer can log in to the Professional Edition, but your bank card account will not be affected.

I can reapply at the counter of China Merchants Bank with a valid account opening certificate and one-card card, or I can reapply at the counter after voiding the professional certificate (click "System Settings"-"Void Key").
