Likely something turned on firewall behavior.
You can check out this theory:

     On your background, right-click
       and "New Shortcut" then browse to "C:\Python25\pythonw.exe"
                       (or wherever your Python is).
     When that shortcut has been made, right-click it, and change
     The "target" from:
          "C:\Python25\pythonw.exe -m idlelib.idle -n"

If this shortcut works to give you Idle, the problem is in creating
a separate process linked via a socket to "localhost" port 8833.
