Need Adobe Audition (ver. 1.5 ONLY) help with Direct X plugin.

I have an Adobe Audition technical help need.
I'm using Audition 1.5 (I know its old but I LOVE it)
Up until about a month ago, all my Direct X plugins were working. Now.. No.
The Direct X menu option doesn't even show up.
I am using the exact same version on my Laptop and everything is perfect. Everything works fine.
I need help (a screen sharing session) to help me get Direct x plugins working again on my main PC (Windows 10)
