Can't plug Kontakt 5 as a VST~

    Sep 28 2012 | 11:04 am
    I'm trying to use Kontakt 5 as a vst in max 6, but I get this message in the max Windows : Kontakt 5.dll : no format VST exists. I use Kontakt as a vst in other software (sonar), and I think I already use it in max aswell.
    Do you have any cue?
    Last time I get a problem with the vst~ object I solve it deleting Max 6 preference file, but this time it doesn't work.
    Any help would be welcome!
