New to Hashcat, command starts and then stops after a few seconds

I am very new to hashcat, but I am trying to learn. 

my command is this,  .\hashcat64.exe --force -a 0 -m 0.\hash.txt .\rockyou.txt 

rockyou.txt is a list I found off of the internet, because I couldn't get the default one to work for me

Anyways this is the output that I get


bonus question, is there a way to specify password length?
