hello all I managed to solve the issue by doing the following 
 
	 
 
	beta C:\Users\yourname\Saved Games\DCS.openbeta
 
	 
 
	example C:\Users\yourname\Saved Games\DCS.openbetabackup
 
	 
 
	restart DCS allow it to create a new one, redo your settings and test
 
	 
 
	You can move your input folder back after to save time from the renamed one.
 
	 
 
	 
 
	and it worked !
