Alpha Track or Tranzport Nu 6

Pls help! I need to use Alphatrack or Tranzport on win 7 Nuendo 6!
I see it bumping the midi meter but nothing happened.
I see people posting it works for them but I’m completely stumped. Loaded drivers from Frontier Design but no deal.
If you know how to get this pair working I’d be a very happy man.
I’m frustrated to say the least!
I’ve used both of these in earlier version with no problems.
