Failing to connect to local host!!!!!

JimmyTeeRock | Edit | Show History

Hey guys and girls,
please help me if you can.
It's a simple click once deployment ("check for update") to my own local host, I was doing one of those "How to videos" on checking for updates.
I have all the IIS components installed. As you can see from the error message below: it isnt actually saying anything, ie, what the *** is %1 ????
Anyway, I had it working, ie, I could do an update, re-publish, then go and check it and it was working fine.
But now I cant get past here:

Error 1 Failed to connect to 'http://localhost/Radio/' with the following error: Unable to open the Web site 'http://localhost/Radio/'. To access local IIS Web sites, you must install the following IIS components:

%1
In addition, you must run Visual Studio in the context of an administrator account.

For more information, press F1. 1 1 Radio

Please tell me if you need more info.
It's visual studio 2008. Check for update app publishing to my local host, ie, not a server on the web as such.

**** Visual Studio is definately running as administrator as well, so that part of the error message is wrong too!!!!

Arrrggghhhhhh!!!!!

Please help.
