No managed to install FCKeditor in my website.

Hi All,

i downloaded FCKeditor Ver 2.5.1 from http://www.fckeditor.net/download, I extract the zip file into c:\inetpub\wwwroot\, after that i tried to access this url, http://localhost/fckeditor/_samples/default.html, and i click on insert/edit image, i got a pop up window http://localhost/fckeditor/editor/fckdialog.html, and i click on upload tab, and browse one image file to upload, i got a error window saying that 'oUploadAllowedExtRegex' is null or not an object, url http://localhost/fckeditor/editor/dialog/fck_image.html, May i know what is the error talking about? how to solve it?

another question is,
if i have a asp page call create.asp and it is under c:\inetpub\wwwroot\, and i access it through http://localhost/create.asp, May i know how i unclude fckeditor in my create.asp page? treat the fckeditor is installed in the directory that i mention above. Thanks a million
