For some reason, the license deactivation is not working - it reports a connection problem. He has turned off his firewall, and also tried over a cell phone data tether. No cigar.
The easiest way to debug this problem is to have the user type "wyday.com" in Internet Explorer. My guess is he is blocking our site (either in his router or somewhere on his computer).
So - please - any suggestions? What can I advise him to try, and is there a way I can get this key off his machine, so that at least I could give him a trial extension or something to keep him going for the time being.
There's the "DeactivationRequestToFile" function which deactivates without an internet connection.
