Unable to open the activiti explorer

[bpmdesinger]

I have downloaded the activiti 5.10 and i run the demo setup, by typing

Ant demo.start ‍

in the CMD command line and it gave me that "Build Successful". but when the http://localhost:8080/activiti-explorer opened automatically it showed me the following error:-

HTTP Status 404 - /activiti-explorer

type Status report
message /activiti-explorer
description The requested resource (/activiti-explorer) is not available.

So what might be going wrong?

Look into the tomcat-log (catalina.out) too see what could have gone wrong.
