Guys help. Trying to download a *******. I'm at 96% na, I have 68 peers, 10 of them seeders. I'm downloading and uploding. My problem is from time to time, I will get a bit******* error and it will stop. I have to resume or force start it to get it going again. Sometimes complete stop and I have to exit bit******* and restart the program.

This is the error from the log file:
Traceback (most recent call last):
File "Bit*******\RawServer_twisted.pyo", line 512, in _make_wrapped_call
File "Bit*******\Connector.pyo", line 963, in connection_lost
File "Bit*******\ConnectionManager.pyo", line 441, in connection_lost
KeyError: '80.43.117.54'
[4.22.1 2006-12-15 21:39:50] DEBUG : ******* failed

Whats the problem and what should I do?
