Did you respond directly to him, or did you do it through the eBay messaging system?
Once a dispute has been closed, it is very difficult to get them to re-open it, which is why it is so important to respond promptly, and through the dispute system (not directly to the seller).
With recent changes, buyers actually have 180 days in which to raise a Significantly Not As Described (SNAD) or Item Not Received (INR) dispute.
Perhaps it would help if you updated the "Location" field in your profile?
