The DHT function is not working on my pc.
I have no router and I am using a 3D wireless dongle with windows xp as the os.
I have reloaded Tixati with no change.
DHT used to work fine before the last update.
Can anybody help?

I've it working since day 0, not sure what might be in your case but probably ISP.

Push the DHT button on the top of the client. What does it say for status? Is there a node id #. Is the Start button available?
Under that are tabs click the last one, log copy and paste that here.
