Ah ... that's typical of ISP filtering & Rogers does filter against particular users. They have admitted it in public to filtering p2p users. So you may be the odd one out who they chose.

You could try changing both a connection & listening port around the range of 49152 - 65535. Try 64049. Go to LW's menu bar, Tools>Options>Advanced>Firewalls & change both port boxes.
