Coldfusion 11 administrator

I am having trouble accessing the cold confusion 11 administrator. I am using:

http://127.0.0.1:8501/CFIDE/administrator/index.cfm

I get:

A message stating page cannot load.

I have tried several browsers, turned of my anti-virus software and firewall but still nothing.

Can you please shed some light on this problem. I have an assignment due shortly that I really need it for.

Thank you in advance.
