I have a problem with my \teamspeak3-server_win32..

Once I have started the server I cannot restart it.
After the second start the server stops with: logging to file started (no console logging on windows)
The server can only be restartet after deleting the file ts3server.sqlitedb
But this file contains all the settings for the already created rooms.
Is there a possibility to restart the TS-server without having to delete this file or redoing all the settings?
Getting a Non-Profit-Licence and copying it into the above mentioned folder doesn´t solve my problem.
Can you help me with this?
