Mike...
Thanks for your kind reply.
My DAW does
not have, and will not ever have, an internet connection.
Further, this means that my internet connection computer -- not the DAW
computer -- does
not have CCC installed.
So I do not use CCC.
After a few hours I bit the bullet and downloaded again.
You must understand that here high in the Rockies, out in
the remote high forest (great moonlight on the snow tonight
by the way) we have connection speeds powered by slow squirrels.
So it is an investment to download what would be, in the cyber city,
a few minutes.
It turns out that the file was indeed corrupt!
The posted MD5 is correct.
Thanks, everyone who noticed, and Mike
for your response.
