I recently installed the latest interface which functioned well.However before I could use the 737NGX I found I had to use my activation code.
Every time I used both types of NGX I had to reactivate. Removal of the interface did not solve the problem so it looks like I will have to reinstall as PMDG are denying me the use of their product because of toomany activations!!!
Is this a fault of the interface? Anyone have any ideas?
