Server admin privelage

Hello. I tried to run my own Teamspeak server today, and when i join the server, and try to add the privilege key, i am told it is incorrect or has been used, and it hasn’t.

I also cannot add myself as an admin on server query, because when i try to login using Putty, it just closes the application.

Got it sorted.

Closed my TeamSpeak Server through Task Manager.

Deleted my TeamSpeak server files.

Did a re-download, and it worked.
