well… now it works !! i dont really know what have changed…!
one thing i have noticed, this time it warned me that the SKI license is going to expire in 30 min on C7.5 startup… 
( i dont know why there was any expired programs, i have full licenses from steinberg,and it gave me strange message later, your Cubase 7 license has been expired !!)
anyway,i was able to use cubase with ic pro, after an hour i quit cubase, made maintenance on elicenser, now cubase start up normally with SKI Remote.
so maybe its something related to bad licensing? i dont see it now on elicenser anyway now that all works 
go figure.
hope it stays O.K
Cheers.
