To update, I thankfully received the licenses, and they showed up in my license manager under the HD500x. I authorized the computer and pod, installed them to the hd500x, but now I'm not sure where to find them. This is probably a noob question, but I figured the amps would be in the drop down of the amp selection in editor.
Edit: also went to setup page 12/12 on the LCD screen of the pod, says the packs are there, so it's probably something simple I'm overlooking
