This is a text-only list, so we will not be able to see any pictures.

Does the error message look like this?

            "Subprocess Startup Error",
            "IDLE's subprocess didn't make connection.  Either IDLE can't "
            "start a subprocess or personal firewall software is blocking "
            "the connection.",

Then try starting idle from the command line with the -n option. If it 
starts there may indeed be a firewall that you have to reconfigure. 

(If it still doesn't start there may be a module written by yourself hiding 
a necessary part of the standard library -- but first check for the 
firewall.)
