Problem with licence

Hello, I’m using eM Cient free, and today, when I started the program I’ve got a message saying that I have to renew my licence. I’ve visited the link on the message and when I tryed to get new free licence it says that the licence for my mail is already excists and that I can only use activation code. My problem is that I’m offline now and I can not get new activation code. Please help!
