Rogers are known to be anti-p2p, but my understanding is they don't apply their shapers or blocks on all users ... only the high level users or perhaps in certain regions of their domain.
Try changing the listening port LW is using to a higher number between 49152 - 65535. A good one to try is 64049. ie: go to LW's menu bar, Tools>Options>Advanced>Firewalls & make the change there. Then restart LW.
If no good, then you could try deleting your LW Preferences folder whilst LW is
closed; instructions here:
Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.) But this will mean you will have to reset "all" your options again once you re-open LW.
Your Webstar, is it port forwarded or does it have UPnP enabled? Did you ever change anything in its settings?
Not sure whether your model has an internal NAT firewall or not. But you could always try forwarding a port if the above fails:
