Getting error while running command --> python ccm start on Cassandra cluster manager Windows 7 64 bit

Question

Hi I somehow managed to install ccm on my windows machine.While running command --> python ccm start I get an error as

UnavailableSocketError("Inet address %s:%s is not available: %s" % (addr, port, msg)) ccmlib.common.UnavailableSocketError: Inet address 127.0.0.1:9042 is not available: [Errno 10013] An attempt was made to access a socket in a way forbidden by its access permissions    

My ccm is stored in this folder--->C:\ccm\ccm-master

Following are the steps I am doing with CCM :-

1.C:\Windows\system32>cd C:\ccm\ccm-master     

I am creating a new cluster like this

2.C:\ccm\ccm-master>python ccm create test_cluster -v 2.0.9    
Current cluster is now: test_cluster

Adding 2 nodes to the test_cluster like this

3.C:\ccm\ccm-master>python ccm populate -n 2 

I am checking the status like this

4.C:\ccm\ccm-master>python ccm status
Cluster: 'test_cluster'
-----------------------
node1: DOWN (Not initialized)
node2: DOWN (Not initialized)      

as both the nodes are down , so I run this command to start cluster .

5.C:\ccm\ccm-master>python ccm start     
Traceback (most recent call last):

ccmlib.common.UnavailableSocketError: Inet address 127.0.0.1:9042 is not available: [Errno 10013]    An attempt was made to access a socket in a way forbidden by its access permissions  

So can anyone tell me why am I getting this error ?How I can make it work ? any additional settings are there , that I forgot to do ? Please provide valueable solution Note- my firewall is off and antivirus is disabled still I get this error.
