Changeling

Hey everyone, I am super excited to find this place. I have followed all the instructions so far for installing/running the game. I get to the login screen and get the INV-300 error. I have done everything up to and including installing the new security certificate as the FAQ said (it was successful as far as I can tell.) So now I am out of options for helping myself and am posting here as the FAQ said. Thanks in advance! Changeling
