Got ES4 SP1 Installed, Email, Email service, Complete task Email endpoint configured correctly. Just cant get any email to the users when they are assigned a task..Can send emails when using EmailService, Send With Document that works perfectly.The Task Notification service may not be working at all..¿Any clues or testing to be done?

I have downloaded ESD for LiveCycle ES4 and it does NOT include a self-running Quickstart jar file, com.adobe.granite.microcore.jar, in the \CRX directory¿Can the ES3 version be used?
