I installed FT on my portable hard drive and put in the license and it works great. I tried to run it from the protable hard drive today at work and I got a message that I had to be signed in as the administrator and reinput the license code in order to play. Everything is installed on the portable hard drive and when I want to play the game I have to go into the FT folder on it and click on the icon? I can't be the administrator at work. Thanks.
