Black screen with only sound under pluzz.fr

I've just installed pipelight (v0.2.8) with schockwave flash 18. It works fine with m6replay.fr, arte... but it doesn't work under pluzz.fr. I get a black screen with only sound after I click on screen. When I tried with Adobe flash 11.2, it worked under pluzz but not with others.

How can I do without use Adobe flash 11.2 ?

Thank you for your help.
