I have just tried to start tb2013 and got a message saying my license was out of date, with instructions to connect to the internet and try again.
I was able to start the game at the third attempt but I hope this isn't going to happen every time I start up the game.
Out of date license

Re: Out of date license
I've re-started the game several times since I posted this and the problem hasn't re-occurred so it looks as if it may have been a one off glitch.
