How do you update Altitude game server.

i assumed restarting the server would update it, but when i tried ./startstart.sh nothing happens. i also tried the ./server_launcher and received this error

Debian Linux 5.0

jiggly@Tellnet:/home/games/altitude$ ./server_launcher

Launcher Error

Looks like a corrupt install: after installation there should be a file "launch-server-launcher.xml" in the base altitude install directory. Please reinstall from the latest version here: http://altitudegame.com/download.html

To start the server (which will automatically update) on a valid installation you should just have to invoke ./server_launcher, as above.
