I have tried everything I can and am still getting connection timeouts. Can anyone help? I tried Passive, I changed my port to a different port, I ensured UPnP is enabled on my router, and I still can't get this thing to work. What am I doing wrong? I did absolutely everything the guides said to try but nothing seems to work. Any help would be much appreciated. I can send and receive messages, but can't download any files or lists, and yes, I have done the registration correctly in hubs that require registration.
