Thanks for your interest, and I now think I've sent you the download link (guessing from your username!). Thing is, I like to make sure I know who is using the software, so I don't get random and unexpected enquiries about what's going on. Therefore, I encode your DFE number into the system as a valid user.
This will become more important in September, when I attempt to charge for the package. It'll be free for the system as is now (with a recommended £100 a year donation), or £500 per year for the premium version, which will come with a heap of brand new features. This will be free to demo until October half term (and if ordered before then it'll cost just £250 for the 2016/17 academic year).
