Guide on Modeling and Executing BPMN 2.0 process using Software AG Designer 9.6

Hello,

I want to model a business process using BPMN 2.0 in Software AG Designer 9.6. After reading a lot about BPMN 2.0 creating a Business Process Diagram seems to be straightforward. So I modeled the business process. Now I want to execute the created process. Can anybody provide me more details on how to do this?
I searched a lot for information in the internet but didn’t find anything.
I am currently using webMethods in a project at university.
Any help would be great (i.e. high level description of the steps to do, tutorials, guides and so on).

By the way - after installing the Software AG Designer 9.6 calling Help > Help Contents in the menu displays me a Software AG Designer Guides book. By opening the webMethods BPM Process Development chapter a lot of links don’t work. Is anybody of you facing the same problems. Analyzing the hyperlink I got something like http://127.0.0.1:51271/help/topic/com.webworks.eclipsehelp.webMethods_20BPM_20Process_20Development_20Help/proc.creating.processes.html?cp=14_10_5_3. Do I have to start any server to access that information?

The same resources as in the Eclipse Help Contents can be found under http://techcommunity.softwareag.com/ecosystem/documentation/ as PDF.
