QTR-Quadtone RIP

Hello, I am new to the QuadToneRip which I am running on my OS X with
PSCS3. My Epson 2200 is connected to my intranet using an Airport
Express base station.

Note that I can print to the printer using the regular Epson driver
without any problems.  However, when I try and print using the
Quad2200 driver i get the following message: "Network host XXX.XXX.X.X
is busy, down or unreachable: will retry in 30 seconds"

Does anyone know how to solve this problem?

Possible related issues, for which I do not have an answer:
1. I did pay the required $50 for the RIP, so I am really miffed it
did not "work as advertised" - is there anyway to check that my
version of the software is indeed active, do I have input a code
somewhere to activate it? If so, where do ii find the code (purchase
via paypal etc)

2. The print dialog has the following reminder: "Did you disable color
management in the print dialog?" - How am I supposed to do this in
PSSC3 when you I am printing using the RIP as there is no color
management settings listed under the print dialog associated with the
 RIP.   


Kind regards
