Thanks for that info fireberd!
FYI:
I received a reply from Cakewalk with a set of different download links to try and the result was the same limited DL speed using Firefox 31.
By chance I tried a spare laptop that is not used much and still has FireFox 25.1 installed. Surprise, the single file came down at 3.4MB/s vs. 1.2MB/s using FireFox 31. My guess is something got broke in the newer versions of FireFox.
Anyway, I now have a couple of different options by using FDM or using the older version of FireFox on the other Laptop. What started out as an issue has become a win-win. I learned some things and have resolutions to my issue.
Again, Thanks to everyone that replied!
Kind regards,
Rick
