Export process as BPMN file and open with Eclipse Luna - BPMN 2.0 / error

Hey guys, i have a little problem that i hope you can help me.

Actually im working with Bonita 6.4, but my problem start when I exported a process as BPMN2.0 format, with the objetive to view this process in other tool (Eclipse Luna / BPMN Plugin) but when I try to import this file on Eclipse, many errors like "Could not find BPMNDI information" are shown.

has bonita problems with the BPMN Format?

I analized the file with a xml reader, but i really dont know whats the problem.
