So I re-read that logfile and it is a huge list of two repeating sets of lines. Below I will post those two sets:

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 679, in __init__
  File "subprocess.pyo", line 896, in _execute_child
WindowsError: [Error 267] The directory name is invalid


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 679, in __init__
  File "subprocess.pyo", line 896, in _execute_child
WindowsError: [Error 2] The system cannot find the file specified

These two groups appear in no (at least to my eyes) apparent order throughout the logfile.
