Project5 v1.5 Cyclone Patch Needed

I sure hope someone can help me out. Here's my problem...
 
I can't find my copy of the Cyclone patch.
When I originally purchased the boxed version of Project5, I had to download the patch from the Cakewalk site.
A link to the patch is still here on the site, but I get a "page not found" 404 error when I click on it.
I contacted support, but since it's such an old product, I've heard nothing.
 
I have an old DAW with lots of really good legacy audio software on it, and Project5 used to be in that list. But somewhere between then and now, for whatever reason, I uninstalled the program. And of course, as luck would have it, I can't find my copy of the patch now that I want to do a re-install.
Project5 was very useful to me (including Cyclone), so I'd really like to get the patch, or least be given some idea of how to get the program to recognize Cyclone. 
 
I plan on keeping the old DAW as sort of a backup system, and having Project5 on it would certainly help.
 
Thanks in advance.
