Nope, I get an error and X3 pro shuts down... SampleTank wants to load as an FX. I set it to Synth but it still shuts down X3.
I have tied many things, too many that I cant remember them all.. Administration settings, rescan VST.
On a side note, it works great in Sonar 8 in Win 8.1.... I have notices that the VST in Sonar 8 and X3 are linked as one so changing setting in one or the other changes them in the other I don't know if that has anything to do with it??? HELP!

Win 8.1.
peace!
