Can't Login to garrysmod.org

I can’t seem to login and download files from garrysmod.org, as when I try to do so by clicking the “login using steam account” button and login, it tells me I do not own Garry’s mod when I clearly do. Any help?

Is your profile set to private?

EDIT: Wow, I can’t believe I actually ninja’d someone.

ninja’d

I just checked and it was set to Friends Only. Changed it to public and it works now. Thanks for your time.
