That means chrome is already running.
Kill the chrome process, then try again.

Here is an example of how to kill a running process. Use it carefully and sparingly, only if you cannot find the chrome window.

Code:
me@mysystem:~$ ps -e | grep chrome
 4473 ?        01:33:36 google-chrome
me@mysystem:~$ kill 4473
me@mysystem:~$
