I have installed the webpart and I am recieving the following error in the webpart

An error has occured with this web part. Please contact your system administrator and relay this error message: Invalid URL: /.
My site is a top level sites but sites at http://servername/sites/sitename.  No matter how I enter the path in the admin list area, I get this error.  If I create a top level site at http://servername/sitename I am albe to get the webpart to work.  Does anyone know of a way for me to get it to work at http://servername/sites/sitename?  Thanks.
