Why is my account, but also registered a replacement computer?

Honestly, I hope machine translation gets better in the near future so I have an excuse to be unemployed and also so that the world can communicate more easily.
This guy is chinese. I think I can understand what he is trying to say. I believe what he is saying is, why can't he log into his wallet account from another computer.
Answer: You need to copy the wallet file xxx.wlt in the old computer to the NEM\NCC of this other computer to be able to access your account.
My guess of what he is trying to say.
