SCORM content won't launch on LMS

Hi, I'm new here and I have a problem with some module.

I usually use Articulate Storyline 2 to create SCORM content and upload them on Moodle. I have a new client who is unable to launch my SCORM contents on any of their office computers. They just got the loading page of the module forever. I used debug mode to find the matter and I ended with this :

I looked at the same debug on the computer we use at our office and I got exactly the same debug, except that the module load successfully and the debug continue above the line 149. It seems the "Returning Incomplete" stops the loading on their computers but not on our.

Do you have any idea ?
