Help about WMS connect to Analytic Engine

Hi,

 I am using webMethods7.1.2 .When I start WMS,below error "unable to load file [URL]http://10.191.xx.xx:12503/services/rule.wsdl[/URL]" occurs. I can login WMS [URL]http://10.191.xx.xx:8585[/URL], but I can not monitor anything. It says, "Error when execute searching.Please verify the configuration of Analytic Engine at "Mnagement->My webMethods->System Configuration"".
 Is there anyone who can help me for this issue?I need your urgent assistance.
 Many appreciation!
