The IP or A Record provided does resolve to a traffic Z server (http://64.34.46.60/) and will deliver a page in a browser but it appears that your url is not setup at trafficz to resolve as a virtual host.
I would verify that you can see these domains in your trafficz account and if so - it is a problem at trafficZ.
I recently moved to TrafficZ from Sedo and it is probably too early for me to tell but I do see a trend - More clicks here but the clicks pay less thus far.
