Connection Time outs

[mct09003 0]

I have been trying to connect to a few public hubs and have been unsuccessful in downloading/uploading anything from only select hubs.  I can download and upload from a couple hubs but i have just added a couple new ones recently since i updated versions and all my attempts have been unsuccessful thus far.  I registered with the hub, added it to my favorites and can search but when i select something to download it shows up but is always "connecting...." or "connection timeout".  DC++ has been allowed through my firewalls in settings and control panel.  Is there something i am missing or am i doing something wrong?
