Here's some news :
I've downloaded another version of Primo 2.4.
This time, I can launch Primo, until the language choice, and then, my device reboot.
Some people on the web said the problem is about license, but I've only 2 licenses in my folder. I've tried to copy license from "complete primo version" (link in post #11) but this time, my device says "Out of memory"
SO maybe problem is license, I should find a good one...
