So in summary, don't connect to the internet until after the program has loaded and you get the TechSmith server message and it works completely fine. I gave it a shot, I turned the internet back on after starting up the program and getting the 'could not connect to TechSmith servers' message and waited with my fingers crossed and it seems to work completely fine and recognize its self as the full version and it hasn't pestered me about having an invalid key so I'm a happy chap. There may be (better) third-party firewalls for these purposes, but we'll see. It still tries to connect to the internet. I tried blocking the program in the Windows firewall, but it didn't work. Yes, in that case you may end up with problems. The problem is that the game I want to record footage of requires me to be online (.)
