guiminer cannot start mining if I start it from command line

[linkstack]

If I start guiminer from command line and click "start mining" button, nothing happens. And when I close guiminer, it pops up a message box saying "it has written error message to guiminer.exe.log"

Following is the traceback from guiminer.exe.log:

Traceback (most recent call last): File "guiminer.py", line 860, in toggle_mining File "guiminer.py", line 1008, in start_mining File "subprocess.pyo", line 672, in init File "subprocess.pyo", line 787, in _get_handles File "subprocess.pyo", line 826, in _make_inheritable WindowsError: [Error 6]

I have the first problem but not the second.
