V-Vocal is greyed out and i can't use it, How can i solve it ! Got sonar studio X1 with the last patch an im using windows 8. All drivers is up to date..

You have to have a clip or track selected ie highlighted before you can use V-Vocal; also it can' be a groove clip or have audio Snap enabled at the same time.
 
Also win 8 is not yet released let alone supported. While there will be a patch for SONAR X2 there certainly won't be one for SONAR X1.
 
Really need a it more informatin about what you have done.

It is selected, but still greyed out..

Bounce to clip and try again

Looks to me like that is a groove clip (rounded corners). They are also incompatible with V-Vocal. Either turn looping off or as Bristol_Jonesey suggested bounce to clip

Did that on both track's re-bounched down , then saved and reopened again. edited :( My bad, just did 1 track.. )

"Rounded corners"

This is the visual confirmation that it is indeed a Groove Clip.

Here now they'r ordynary clips .. http://imageshack.us/a/img268/5710/vvocal.jpg , but still problem ,any other solution ?

Audio snap active? Open the inspector and have a look at the audiosnap tab (under the clip tab). Audiosnap should be unchecked.
