seems like you have that error because of either the php configuration or since its on windows. i have 0 experience with php on windows.
i found this on the phpbuilder mailing list..
"Thanks, but I managed to get it sorted. I had set the doc_root AND used
cgi.force_redirect and only ONE of those should be used. As soon as I put
';' befire doc_root, everything worked."
try changing those values around in the php.ini to see if you can get it working.
