Hi,
Same problem here. Connect360 was working beautifully for week, then, after restarting the computer, simply stopped working, and error message concerning ports 1900 and 9335 appeared. Have installed no new software, done nothing different, my firewall is switched off, all Xbox router settings etc identical to before. Tried looking for the Twonky media software, but have only ever installed Connect360, so it is not there. Here is a list from my activity monitor:
Activity monitor
AppleSpell.service
ATSServer
Connect360 helper
Dock
Dropbox
Finder
Firefox
GrowlHelperApp
Hear Daemon
Hotspot Shield
ITunes Helper
launchd
loginwindow
mdworker
Pages
pboard
Spotlight
SystemUIServer
UserEventAgent
I really loved Connect360, can anyone spot anything here that would conflict/block the ports specified? As an afterthought, installed and tried to use Rivet, but my Xbox doesn't even see that.
Any help would be greatly appreciated!!
