QTR-Quadtone RIP

I'm new and testing both a Epson 2200 and your driver.  I had the driver installed and 
working but changed the black ink cartridges from black to matte which required me to 
remove the printer - Epson 2200 from the Print Center and then add it again.  Note, the 
Epson 2200 driver was not uninstalled.  Problem, when I went to use your driver it no 
longer shows in the list of printers.  I tried to uninstall but get a message that a new 
version is installed and it won't let me uninstall.  I tried to just install QTR again but still 
does not show as a printer.  

How do I uninstall QTR?

How do I use QTR when I have to swap the Photo Black and Matte Black cartridges?

thanks
