From today, a new registration policy will be used upon non-confirmed registrations. In order to download here, you need to register for free and confirm your email address by clicking a link. If you do not do this, your account will not be active and then you cannot download.
I have just removed 1041 accounts from my database that have not been activated. You will need to activate your account within a month, which is a very long grace time, and if you don't your account will be removed. If you have not received your activation link, you can send me a message and then I can fix that for you.
LT;DR: Register, activate within a month, profit.
Have a nice weekend and I hope you can find the information here that you are looking for!
