I have had mine work just fine from v8.5 all the way through to the current version, and this includes X1, X2, and X3. No issues save one small one with the installation of Platinum on top of X3, which was easily fixed and well documented here on the forums (see my thread start list). I am glad I am getting this much mileage out of my V700 Studio setup... very grateful actually, considering my investment into it.
