You can set you default torrent client, but Please don't make it Limewire.

Use either uTorrent : Torrent - a (very) tiny BitTorrent client Which I use and recommend, or check out Vuze : Vuze: The most powerful bittorrent client in the world.

These are Highly recommended torrent clients that are Whitelisted at almost every tracker, both Private and Public.

Hope this helps.
