I sign in my home computer, and also login my office computer. But later, the office computer RaiDrive showed because had sign in home computer, so the office computer Login failed.

Hi~ @Jin_Feng,

Yes, If your account has only one SESSION. You can increase the number of a concurrent login sessions by buying more sessions.

If you have one session, then another logged-in session will be logged out automatically after logging in.
