Just upgraded to Platinum.
 
Unable to play VSTs via MIDI keyboard.  Control surfaces move screen counterpoarts so MIDI data is being communicated.  Opening the VST interfaces allows hem to be played with the mouse so there doesn't appear to be an audio issue.
 
Has anyone seen this problem?
 
Thanks.

make sure your hardware is routed correctly in preferences and in track I/O's
can you give some details on your spec's please ?
 
what midi controller ?
what kind of audio interface ?
 

If the control surface is part of the keyboard, and spinning controls makes the MIDI track's meter move but playing keys doesn't, then it could be that Notes is disabled under preferences > MIDI > playback and recording.
