Cant access CF admin

["zac1234"]

Hi all,

 i'm struggling to access my CF admin (or any of my sites in IIS) I'm using 
CF8. 

 all i get is: [b]Either the Macromedia application server(s) are unreachable 
or none of them has a mapping to process this request.[/b]

 i'm not sure what to try next. ive tried using the web conf tool to detach 
then reattach IIS. ive checked all the folder locations of CFIDE and my sites.

 i'm well and trully stuck and i'm supposed to go live with a new site 
tommorrow! please help

 thanks

 zac
