Hi Bob , Many thank you for your answer, in that project i have many VSTi plugins, until now with the first 5 i can open the project without crash, 
	i have to re-open the project until i find the bad one ! i'll let you know which is ;) 
	I think to have only 64-bit plugins but i check also that thing  
	 
 
	In the screenshot i've made you will find the error i attach here :
