Hello, I currently have 2x6950 in crossfire, i7 2600k, 11.1a drivers, ATi Stream 2.3.

When I try to run it with the following parems:
poclbm.exe --user=x --pass=y --host=http://mining.bitcoin.cz:8332 -d 0

•      Cayman
[1]     Cayman
[2]            Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz

It gives me this error:

InvalidURL: nonnumeric port: ''
Unexpected error:
Traceback (most recent call last):
  File "BitcoinMiner.pyc", line 171, in mine
  File "BitcoinMiner.pyc", line 157, in getwork

Any help? Thanks!
