Grades repport doesn't work for SCORM 2004 generated by Articulate

We are generating SCORMs 2004 with Articulate Presenter 5.0 in Moodle 1.8 and we are suffering problems in order to give visibility to the students about their progress and results.

The grades are set properly, because as a Teacher I can get an overview of the progresses, with the limitations of Articulate, but the students can't see anything.

I've tried several options when I'm attaching the scorm but this also doesn't work.

I attach two screenshot, maybe it will be helpful.

Thanks in advanced for your support.
