Today I did the server update 3.3.0 but I failed my backup so I lost my Teamspeak but it's ok I will do another.
Nevertheless, a problem remains I've removed the lasts files of my teamspeak and I install another one in new files and now I can't start him normaly (like
./ts3server_startscript.sh start
because he say "teamspeak server cannot start") now I need to do
and I can connect to my teamspeak but another problem (again) when I do
./ts3server_startscript.sh status
he say "no server is running (ts3server.pid is missing)" so I try to do some thing like
touch ts3server.pid
and he say "Server seems to have dead" and now I don't know what to do to leave it like that.

Thank you for taking the time to read all this and thank you for your help.

Goodbye, Nessar.
