Hello,
You said: "Everything is configured in Workflow customized settings"
Obviously, this was not the case. SWU3 should have shown you that the SWWERRE was not running. Your workflow administrator (if there is one) is not doing his job.
Why do you think there is a problem now with the user decisions? What state are they in? If all is well, then they should be in READY state. You should show the chronological log, it's much easier to understand.
