I am on the same boat here. I bought Pilot2ATC in late december (i've been charge on the 31st of december), but I am still waiting for an activation key.
I am in no hurry, and i completely understand that you may need time to rest and recover.
But do you have any idea about when you will be able to go back to buisness?
I hope i've not been rude, english is not my native language.
