FCK 2.0 RC2 / CFMX / XML 500 Error

I am attempting to use FCKEditor 2.0 RC2 on CFMX 6.1 w/ Win2K3. Everything works fine until I load the resource browser via the browse button in the image properties dialog. When the resource browser loads, I get a javascript pop-up saying:

XML request error: Internal Server Error (500).

I have made the following changes to the fckconfig.js file with the following lines:

// Link Browsing
FCKConfig.LinkBrowser = true ;
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Connector=connectors/cfm/connector.cfm" ;
// Image Browsing
FCKConfig.ImageBrowser = true ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Type=Image&Connector=connectors/cfm/connector.cfm" ;

These changes are the only suggested answers I have found and they are not solving the problem. Does anybody have any other suggestions as to why this is not working right?

Thanks
