That's correct. Something is blocking ICMP TTL Expired packets, which is what we rely on for all intermediate hop data. Until something is changed to allow those packets to make it back to the computer, there's nothing you can do to get intermediate hop information.

The fact that hop 1 shows up pretty much eliminates the computer as the problem, so you're going to be looking for a router or device of some kind within a couple of network cables of that computer (cable modem, NAT router, etc).
