SO I followed the pathway and found where the downloads go. You can see in the address bar of my screen shot. There was a Cakewalk file from today. When I clicked it said it was already in use. So I closed the Assistant. And When I clicked I got this

SO does anybody know how big the file is supposed to be? You can see below how big mine was.
SO I deleted them all and I'm running the whole thing again.
There does not seem to be an option on what you download as far as I can tell. You can see it is downloading a file called instruments. That's what you get if you click the big green download button. I just did that with this folder open after I deleted the originals. Both the Cakewalk.exe and Instruments.exe are back but right now show as 0 kb.
Oh , look at this,, The assistant was showing downloading but as I typed this it now shows installing.. I just looked in the above folder and Cakewalk.exe is now 5,644 kb. The instruments are 152,602KB SO why was the versions above totally different file sizes. both of them?
And now the assistant shows nothing happening just like before.
