Spektral Delay for Pro-Tools Upgrade?

Greetings!

I just recently purchased the ancient, unopened Spektral Delay for Pro-Tools software from a legit NYC music store (unopened, on e-bay). I installed it on my G3 Mac laptop(400mHz) in OS9 and it works fine in Pro-Tools Free, but I'm working in Logic Express 6 in OSX and would like to use it there as well.

The problem I'm having is that the most recent software update I've downloaded from the Native Instruments website isn't working. For some reason it won't acknowledge the fully-functional Spektral Delay in OS9 (which has been properly authorized) when I lead it to the folder (which it requests for the upgrade).

Am I doing something wrong or could some alternative way of doing this be suggested? Thanks very much for whatever help you might be able to give.

P.S. Absynth, Reaktor and Vokator are magnificent pieces of work! I'm a big fan of what goes on here.
