Workflow not firing from business process flow

Hi all.

I have a task to run a workflow after business process flow finishes. The strange thing is that the was working and stopped from nothing. To setup this workflow was a problem too, because it started working from nothing as the same way.

What i have already tried:
- Put the workflow to run Sync and Assync
- Put the workflow to run as a child process and not.
- Put the workflow to run for entire organisation.

I have already tried to get the statusChange with javascript but when the status change to complete, the javasript do not run.

Note: I'm using a trial version for 365.
