You are using BitTorrent 5.0.7. Is that the mainline client? It could be the source of your errors. Dime has banned it from its tracker because it was too buggy:

Attention users of client Mainline (BitTorrent) v4.22 and above:

Mainline (BitTorrent) v4.22 and above is anything else but a reliable BitTorrent client. It doesn't adhere to Bram Cohen's own protocol specs of v1.0 anymore, so we had to ban it from our trackers today (April 26, 2007). Sorry for that. See our FAQ for recommended clients.

You should use a better client, like Bittornado 3.18 or Azureus.
