[greengreentree9]

I am new to this Activiti Engine and we are evaluating it to see if it is something we can use in enterprise product. I created a process at https://activiti.alfresco.com/editor/#/processes and the tried to download the xml file by clicking on the "Export to BPMN 2.0" button; BUt I keep getting this error:

<blockquote>
<strong>
File not found

Firefox can't find the file at https://activiti.alfresco.com/rest/app/rest/models/942171/bpmn20?version=1431706881990.

</blockquote>


Any help?

Thanks!
