scoID error on Moodle

Anyone had ever experienced the following error when launching a storyline scorm from Moodle?

"A required parameter (scoid) was missing"

This is happening very frequently ater last update 5, and the problem is that it happens almost randomly. Sometimes when entering the course, sometimes when you close and resume the course, sometime during a quiz bank...

The scorm is set to launch in new window. The moodle patch/fix for rotating view on ipad ios7 has been implemented.

Captivate scorms seem not to have this problem, althought we have not tested lot of Captivate scorm on this Moodle platform.

thank you,
