"Your current profile can't play xbox live" but is payed??

You can also pay the 800 Points charge to change your gamertag on this profile, freeing up the name to be used on another profile. (So no, you can't delete your current profile, but you can change both the Live ID and the gamertag and re-use those
on another profile.)

Says it's connected to Xbox live and it signs me into Xbox live. But still doesn't let me actually play. The message that pops up says this current profile can't play Xbox live.

i bought xbox live gold for 1 month.. but can't play call of dudy black ops on xbox live.. why???.. its says.......The current profile is not allowed to play on xbox live

I don't think it is this, because all five Xbox Live profiles on my Xbox don't seem to work, either. Example: I was playing with my friend yesterday, and he attempted using his profile, but an error code popped up (can't remember the numbers exactly) and
it said "Can't Connect to Xbox Live. Do you want to exit your current session to test your connection?". What also is interesting is that my friend was able to play on his profile perfectly fine on his Xbox. I also noticed that some of my friends seem to be
having this issue, too. I don't think it's my profile. Awaiting to test your steps, though (as my sister is currently playing AC 2) and I will get back to you after I test it.

It tells me that the current profile I'm using isn't allowed to play on Xbox live. My family settings are telling me that I am able to play online but I can't...
