Cant access CF admin

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: Either the Macromedia application server(s) are unreachable or none of them has a mapping to process this request.

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 truly stuck and i'm supposed to go live with a new site tomorrow! please help

thanks

zac
