Ok @paul Gibbs. This fix will be wonderful, since I expected that my site will go online next monday.
When I become a billionaire, I will not forget you. Thank you.

Same problem for me. WordPress Multisite 3.4.2 e BuddyPress 1.6.1

Me too.
You are not alone. I am feeling lost too. When I create a new network I am getting a 404 not found error. I too would appreciate a step by step information.

Can I create a network by simply entering any path? Where do I create sites for the new network?

I have the same problem.
