flash to PHP contact form not working on localhost using IIS

[dpcdpc11]

hi everyone.. i'm new here and this is my problem:

just made a flash based contact form that sends the data to a php file which should be sent by the server to an email address...

it seems there is some issue with my IIS settings or something cause the form is correctly coded and the flash file as well...

and after installing IIS[on vista 64] and then installing PHP and added the PHP to FastCGI handler the form still doesnt work... it just says: "an error has occured please try again" and down in the statusbar says: "transfering data from localhost...'
it seems something blocks the email from being sent from my local host... do i need to change something in the firewall[i'm using the default windows firewall]?? or is something i need to the IIS settings??
