@Notecrusher - sorry you got frustrated looking for this plugin, only to find out after a bunch of time/effort that it is a separately-purchased one that you wouldn't have seen in CCC because it is not freely included with Sonar.
The initial post in the thread indicated in the subject line and content that it was updated - which I am sure was meant to infer that someone would already have to have it installed in order to update it. At the same time - I can also see how you might not have come to that conclusion.
I think it was just one of those unfortunate things - and again am sorry you were out some time and effort with it all.
The Cakewalk folks post in these USER forums to do their best to help us, and when they DO post, it is often quite clear that they do pay some attention to the user posts, and they are often on and posting WELL past their bed time. Please understand how valuable and unusual developer presence in a set of user forum really is. If any mistake was made - it would most certainly have been accidental. Additionally, the fact that nobody else seemed to get caught by the plugin being a separately purchased item would indicate that most folks seemed to understand from the onset that it would have been from a separate purchase (speculation on my part - completely).
It truly is a bummer you ended up looking for something you thought you would have had access to. (I actually recommend you look at purchasing it - it is quite nice).
