I wrote earlier, I am not a charitable organization. I like NAS D-Link and I am loyal to the company D-Link, so for your account gives you access to The add-ones. But it is not welcome freebie!
On the download has limitations. I disabled them recently, yesterday and immediately switched on the user's question ...
Many times, wrote again to inform - if funding from D-Link, will add-ons for free. In the current situation, only because it is - on "free" has limitations.
