blank game via google web store

Hi Forum,

I recently published my first game on "Google web store" and followed the scirra guidelines when compiling it... but my game plays a (black screen of death) and nothing else happens

I'm forced to Task-Manager terminate it. Am I doing something wrong? I've updated my Google Chrome Browser and still nothing.

Thanks for taking time to read this
