Error in running IDLE

[PyGIS]

Hi friends :

I tried to start programming with IDLE .
when i want to run IDLE I saw two error message :
one error is :
"IDLE's subprocess didn't make connection. either IDLE cant start a subprocess or personal firwall is blocking the connection"
another error is :
"socket error: no connection could be made because the target machine actively refused it" .
how can i fix this error ?

Try closing all python processes in Task Manager (assuming you are in Windows).
