Hi,
As Charlie mentioned, first we need to see the manual steps that you followed.
If that is not working, remove all the manual entry that you made in IIS and ensure that connector is also removed using the Wsconfig utility. Once that step is completed, restart the IIS from command prompt and refresh it.
Check all the entries once again and find out if there is any CF entry left in IIS, in case there is any remove it manually and restart. After that check if it is rendering the HTML page, if yes, create the connector with CF and then run the CFM page. Also, check the permission on the folder where you have put the cfm pages.
Let me know if any of the above steps help. Else I will connect with you over a quick call and help you.
