iMessage problem - Can't send to specific contact

[Dhelsdon]

Hi,

Just today this started happening, I can't send an iMessage to one of my contacts. It just says 'Message not Delivered' when I try to send it.
It's happening for only one contact, on both my iPhone 4S and my MBP.

I tested sending an iMessage to another friend and it works fine. Nothing was changed on my end..

I've checked my account settings and they seem okay to me. Not sure what might've caused this.

----------

Edit: If I send from my iPhone it says 'Not Delivered' yet the messages go through and my contact replies.. iMessages on mac doesn't work though

Did you check that contact is online?
