That seems to have fixed it, thank you very much for the prompt and accurate response...the level of customer service is much appreciated!!

I was using Alphatrack with Cubase 4/Windows XP with no problems, but since I upgrade to C6/Win7 it doesn't work at all.  I manually placed both of the AlphaTrackCN.dll files in the Cubase Components folder (the 32 and 64 bit - I have primarily been using C6 in 64 bit).  The Alphatrack shows up along the Windows bar at the bottom, and Cubase is at least seeing a signal (the MIDI in activity bar in C6 lights up), but it doesn't control anything nor is there anything in the display screen.

Thank you for any help!
