First of all I have been torrenting for many years and always get great results from version 1.8.3 so no reason to upgrade. The other day I was not able to connect to anyone. The DHT said logging in but then just stopped. I have finaly found the issue. It has to do with Em Client that I use for email. Once I shut down the email client uttorrent begins to start picking up DHT nodes and all is well again. I noticed on a google search that many others were having the same issue so if your using em client for email you can give this a try. I am currently down loading at 1.2 megabytes a second, as usual. Hope this helps others.
