Mac 8.6 Can't Connect

[jo33bc]

Please help.
I am using OS 8.6
I can launch Limewire Pro, no problem.
Just stalls, although in connection window says connecting to various IP addressess.
Nothing actually gets "connected"
Red light stays on.
No spinning arrows when I do search, nothing.
Used Limewire, before, older version before Pro. Worked fine. Last download a couple of months ago. Downloaded a few MP3's but connection very very slow.
Using a DSL Cable modem, with Shaw Cable in Canada, Alberta.
I believe there is no firewall, if anyone knows differently let me know.
I can see my modem light blinking on my end, I believe that my computer is sending out the information, but nothing is coming back, and no connections are actually being made.
Can someone please please help me :P
