DJM004  Connect360 discover devices no working

I have just bought Connect360 for my mac (OS X 10.4.11 Intel Core Duo) tried all sorts of fixes but still my mac doesn't find my xbox and vice versa. Connect 360 in installed in my system preferences, it sees itunes iphoto and movies in the active service box but no green ticks and no discovered devices. in C360 settings i have everything ticked apart from the enable access control list button. firewall is off but i have the itunes ticked and iphoto ticked as well as setting up a new port button for the following TCP 9335, 2869, 10243 and UDP 1900, 10284, 10283, 10281, 10280.

my mac is connected via air port to a broadband (BT UK) router, my xbox is connected to the same router via a wireless thing at the back, xbox live works fine.

i really want this to work but all the quick fixes people put on don't seem to work? what am i doing wrong? i want to start watching all my HD movies... Please help...
