QTR-Quadtone RIP

I'm just beginning to use QuadtoneRIP to print my Collodion plate negatives
and have a very beginner question involving setting up my software.
Let me explain:
I am using a Mac OS 10.4.9 system.
As I'm living in Japan, my printer is an Epson 4000 printer, which is the 2200 in the U.S.
On my computer I have the 4000 driver and downloaded the 2200 driver from Epson site.
However, I don't see the 2200 driver on my system profiler. I do not see it in applications 
either. I do see Quad200-NK7 in my system profiler. 
Now my problem is when I go to Print, in the Print window I choose QuadTone RIP, and 
then go to select curves, but there are no curves! There is only None to choose from.
I went to the profiles folder and opened Install2200-K7 folder and clicked on install,
but the message I get is: Cannot find an Epson USB printer with the name 2200

Is it necessary to install RunInstall Curves, found in CurveDesign folder, or is there 
something I am not noticing?

Please advise, so that I can begin printing my Collodions.

Thanks in advance.
