Moodle SCORM package viewing problem

Hi, 

I am having a problem using Moodle 2.6.

I had Articulate Studio Pro '09, but upgraded to Articulate Studio Pro '13 like as it had HTML5 capabilities. 

When I publish and upload to Moodle as SCORM Package, I am able to view the course in Administrator Mode as normal.

When I try to view it in Student View, I only see the course appear for literally a split second - and then it dissapears. I don't get any error messages, - just blank screen where the course Articulated Slides are supposed to be.

Please can you advise.

Thanks in advanced.
