I am currently working my way through the tutorial for building a module. At one point when discussing data files it says you need to do odoo-bin -u openacademy  to save the changes to your database. When I try and do this through the command prompt it just moves to a new line with an flickering underscore. I am doing this on a windows machine and my understanding is the syntax should be the following: "D:\Odoo 12.00\python\python.exe" "D:\Odoo 12.0\server\odoo-bin" -u openacademy -d databaseName. 

It has just been sitting there for at least 10 minutes doing nothing, but having the flashing underscore. Am I doing something wrong? How long should this take?
