I had an advanced usage script installed and working up until about a week ago, then the file was inadvertently removed from the server by another administrator. I uploaded the file again and it now resides @ http://www.isabellaoliver.com/io/slurpee.php. When I put that into my preferences in the keyword tracker I get an extremely long error that starts w/ "The advanced usage script URL is not valid." The keyword tracking tool will not function either. Any ideas on what could be going wrong? Tom
