Family settings keep blocking online play on XBOX live...?

[hordage]

I was trying to play Halo 3 online, but it says my profile isn't allowed to play games online, so I unblocked it but still it keeps happening, and just keeps blocking itself again ,and again. . .However my friend's profile on my 360 worls just fine, I would play as him, but I would be ranking him up instead of myself, I don't have a Gold membership and I don't plan on upgrading, my connection is fine also, and my account hasn't expired because I don't pay, does anyone else have this problem? Does anyone know how to fix it?
