Update. I got it, and got it working. I finally learned how to get the download and started it. It ran for about 4-5 hours and never got beyond 40.45%. It ran all night, but this morning was still stuck at 40.45%. So, I started over. Then, I got SONAR Pro to download in less than an hour. It's on my Windows 10 laptop and I've been just piddling with it here for a little while just to see if it works. Well, it works, and so far works great. It's my favorite of all the Cakewalk products, and my first was Guitar Tracks Three, back in 2007 I think it was.
So now, I'm going to take it to the next room in my little studio, connect it to a 32" monitor and have some fun and give it a good work out.
While that's going on, I'm going to see if I can also do a trial of one of the other versions...Artist or Platinum, on my MacBook Pro. There is a place to initiate a download from the Cakewalk site, so that must mean it's ready and available. This is going to be interesting. That is something I've wanted to do for years...SONAR on a Mac.
I'll keep the progress on everything updated as needed.
Thanks again for all the help!
