Error in the Django development server ("runserver")

I'm new to python and django and following the footsteps of "Django Book" I've django installed, including obtaining the following verification to import django in python:

>>>Import django
>>> django.VERSION 
(1, 3, 0, 'final', 0)

I also use startproject command to create a folder with the files __ init__.py, manage.py, settings.py and urls.py.

I also installed the executable pysqlite-2.6.0.win32-py2.6.

However, when trying to check the "Django development server" ("runserver") following the steps in Chapter 2 of Django Book (http://www.djangobook.com/en/2.0/chapter02/), instead of finding the following message:

Validating models ...
0 errors found.
Django version 1.0, using settings 'mysite.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

I find this error:

enter image description here

There is also error when verifying the address http://localhost:8000 ("This page can not be displayed ..." instead of "It worked"). The Funny thing is that I've done it all before (it's the second time I did the installation) and it had worked.

How do I procede to know what's wrong and move foward? Should I uninstall all Python 2.6 instalation and reinstall everything again? (already I tried repairing and it did not work)

Thank you in advance for any help!

Solution

is it you installed a newer version of django then install an older version? you should uninstall them all completely then try installing again.
