Not sure we are talking about the same thing. I didn’t get mine from the DS 4.5 reset but from resetting the Dynamic Clothing Control entry, see below. It gives you a list of files for both 4 and 4.5, again see below. I too paid for 4 Pro so this is what you probably should have as well.
As to whether it works or not I can’t say as I haven’t installed 4.5 and plugins yet.
The Dynamic Clothing Control entry Haruchai lists is exactly the one I reset and downloaded. I have no problem bringing up the Dynamic Clothing tab and performing the draping actions, and I have the Physics tab available so I appear to have the full paid-for version of the plugin available. But…
On machine 1, with DS 4 Pro I have Dynamic Cloth Plugin - Control plugin as shown in M1Plugin.jpg
On machine 2, with DS 4.5 Pro (using the same serial number as the first DS), I have Dynamic Cloth Plugin - Control plugin as shown in M2Plugin.jpg
So, why does machine 2 show this as an evaluation version?
