Can't access Cold Fusion Administrator page using local host

I installed ColdFusion builder and set up the administrator page. I accessed it using http://127.0.0.1:8600/CFIDE/administrator/index.cfm. I logged out.

when I attempted to get back in I got "cannot display page" error in the browser.

I have not changed any configurations on the machine I installed it on. It does have IIS on it but I shut IIS down.

This is frustrating... any suggestions?
