Ipython notebook does not execute anything

Question

I am a newbie in python. I am using python 2.7 version. I installed ipython notebook (version 4.0.0). when I use command "ipython notebook", I get the webpage fine.

However,when I create a new notebook and try to execute something ( very simple things like print "hello world" or 1+1 , nothing happens. The code does not even appear in different colours. It just shows In[*] as I press ctrl+enter or click upon the run button.

Also, I have referred to a similar question here: IPython notebook does not produce output

I tried using ip=localhost, also tried disabling the antivirus and firewall before executing as given in the previous answer, but still no luck. I already re installed python hoping to get rid of this issue.

My OS is Windows 7 and my browser is Mozilla Firefox 41.0.2

Please help me.
