Most downloads also come with an account. Over christmas my PC crashed terminally, so I upgraded it while away, and ended up with a totally clean, but empty machine. I logged into Steinberg's site, and downloaded 8G of Cubase 8, I've got a couple of Garritan samplers - GPO and the jazz band and both of these downloaded ok, as did my pianoteq piano sampler. The other things I use I had to wait until I got home to grab the discs and the serials, and one I could not find - and still can't! Adobe CC subscription was a doddle, and everything downloaded perfectly. My VSTi collection was on one drive luckily, and the only bad news was that the download speed was not the best where I was, but quicker than the post!
From now on, I shall always do the downloads.
