Error after re-install

Hello,
I am receiving the following error after reinstalling, editing conf.ini and allowing appropriate write permissions.
Fatal error: Class 'Dataface_Application' not found in C:\Inetpub\wwwroot\dataface\dataface-public-api.php on line 50
I am using IIS6 and had it working before on this server. I have it working on another test computer (XP).
Your help would be appreciated.
Greg
