I cant receive invite. Help!

Have you run any network test to see what your NAT says? You could also try resetting your modem and router. Sometimes they just need to be rebooted.

To clarify i am not getting no invites at all

I have done all the network tests and reset my router but nothing worked and Xbox live status says only sending messages is out but nothing else. I've also found that my other account on the same Xbox still gets invites and when i tried my profile on a
different Xbox it still wouldn't receive them. So i i think this based around my profile. Is there a setting i must of screwed up with to do this?

Thank you for taking the time to reply back AL.

Just to clarify something further, are you no receiving invites, or are you not receiving notifications of invites?

Invites will still show up in the Multiplayer tab of the
Xbox Guide, so its possible that you may not see the notification pop-up, but they may still be there.

To
change your notification settings, press the Xbox button to open the guide, and then select
System > Settings > Preferences > Notifications.

Go ahead and verify that all your preferences on your account are configured correctly, and let us know if this works for you!

i did what you suggested but it did not work, thank you for the suggestion
