Since update (CC 2015), black screen on launch

Hi,

I have updated Edge Animate yesterday (Yosemite 10.10.3 - MBP Retina). But now, not open, only black screen. I have 2 errors: "(unknown C++ exception)" and "Une erreur s'est produite. Veuillez enregistrer votre travail et redémarrer Edge Animate".

I reinstalled and still not working.

How to resolve ?

PS: Sorry for my bad english, i'm french...
