Your steam account is set to private. We cannot read the information we need if your account is set to private.
To change your profile from private you must launch the steam client. Then once you log in you click on COMMUNITY then on the right side it will have an Actions dialog box. Click Edit my profile. Then click on the Settings tab. There you can change your account privacy settings. Profile status needs to be set to public for our site to read your account properly. We do not need comment permissions or inventory settings changed so you can leave those alone.
