I'm a newb to Sharepoint admin, please be kind..

I sucessfully installed CKS EBE to the server, and the was able to enable the feature. When I go to the site itself, manage features and try to Activate the blogging extension, it sends me to a 403 forbidden page.

I was able to run Process Monitor and find some entries for when I attempted to Activate:

10:25:22.9490396 AM w3wp.exe 4896 QueryOpen C:\inetpub\wwwroot\sites\prod\eritblog\_layouts PATH NOT FOUND 
10:25:22.9493324 AM w3wp.exe 4896 QueryOpen C:\Inetpub\wwwroot\sites NAME NOT FOUND 
10:25:22.9494679 AM w3wp.exe 4896 QueryOpen C:\inetpub\wwwroot\sites\prod\eritblog\_layouts\managefeatures.aspx PATH NOT FOUND 
10:25:22.9497029 AM w3wp.exe 4896 QueryOpen C:\Inetpub\wwwroot\sites NAME NOT FOUND

And indeed there is no "sites" subdirectory under wwwroot. Instead, my Sharepoint installation appears to be at C:\Inetpub\wwwroot\wss\VirtualDirectories\19716.

Any ideas how I can move forward? Thanks for any input.
