Have The Same problem, on windows 7 pc, in Ableton 9 suite the vst runs normal, but it do not connect to sparkle controller, ( message connection failed)
installed several times, switched midi remote sync track midiports on of in all different ways.. nothing helps ..
strange thing the software never asked me a auterisationcode, ( first installed the demo and it worked complete incl .safe etc)
i ordered the controller and end up with the same i had .. ;(
the standalone mode runs good and connect to controller without problem,
ps:
i go direct in usb ports without hub (also tried different ones)
installed 32 bit version
is there any midi remote script for ableton 9 that might solve this ? or does the connection works in a other way ?
