BCM 50, Rls 2.0. I downloaded the keycode for the upgrade to 6.0, over a year ago, and the customer dragged their feet on doing the upgrade. Now they want to do it, but when I go to apply the keycode, I get the error "invalid keycode file'. Do they expire? When I go to the portal on Avaya's site, it shows it still as "current keycode". I dont know if I need to regenerate or what?
