MPC 2

I just purchased a MPC 1+. Everything works fine except I can't run the MPC 2 software. I click to open it and nothing. I had to register ILOK, but it doesn't show the MPC 2 for some reason. Any ideas why it might not be working? Thanks, Mark

Can you confirm your computer OS version?

and if I buy an MPC live 3, could I use MPC2 software with my MPC3 licence?
