For TCP, you need 2.60 or higher. I sent you an email with some instructions on how to upgrade a week or so ago, and then another one yesterday. If you didn't get those, shoot an email to support@pingplotter.com and we'll make sure we get you going.

Just as an encouragement to use TCP, I just tried tracing to hawaii.rr.com from here - and with ICMP, it's not reachable (all hops up to it is, though!), but with TCP, it I get a response.
